The, number 1 sheet (216) has a high magnetic permeability by the saturation magnetization. Number 1 sheet (216) acts in a cover layer stack of a chip inductor, magnetic permeability and high magnetic saturation magnetization thus chip inductor coil protecting and improving magnetic properties can be stored in a first chip inductor. Then, such as also 8, magnetic at room temperature that otherwise does not have a nonmagnetic sheet number 2 (215) for an unexpected guest. Number 2 sheet (215) is a flat plate-like central portion can be formed, Zn-based ferrite or Zn-a Cu-based ferrite material not containing NiO preferably. Next, 9 also such as number 2 sheet (215) in the edge of sheet number 2 (215) is exposed to the chip inductor is later when its cutting line so as to abut a helical coil (241) formed on the substrate. A coil (241) of the number 2 by insulating layer covers the edge or cutting line, a coil (241) is formed on a surface of an exposed portion exposed to carry laminate stack having to be coated. In addition, a coil (241) coil pattern (241) are connected via a conductive via formed on cyclic orbital plane view when rpm, annular track disposed along a conductive via each interval is divided into n when personal reference, one coil pattern (241) is n-a 1 section may have. A coil (241) a chip inductor core around a coil forming a conductive portion of the use of the material, is (Ag) or copper (Cu) etc.. A coil (241) is formed through one of screen printing but the number is not disclosed.

Conversely, magnetic layer (251) content of NiO in much one number 2 sheet (215) to the NiO layer is diffused. Magnetic layer (251) containing 25 to 40 mol % of NiO to when, said number 2 sheet (215) when bonded to a magnetic layer (251) is number 2 sheet (215) ZnO and diffuses from the multiplication by permeability and magnetic saturation (Ms) is equal to the index of a stronger magnetism. Conversely, number 2 sheet (215) include magnetic layer (251) of NiO from diffusion of the NiO to uniformly out of the slowly thereby having magnetism to be coated. The, number 2 by diffusion sheet (215) and magnetic layer (251) both the novel compositions a stronger magnetism and the side of the magnetic sheet said number 1 (216) so that the composition of the similar pre-number 2 sheet (215) of magnetic layer (251) to determine the composition of the substrate. And, magnetic layer (251) promoting the sintering number can be added. The, adding said sintered promoting number since, carry heating process magnetic layer (251) for promoting diffusion of promoting sintering by adding said number and include Bi2 O3 Low melting point oxide or glass (Glass) such as using other. For excessive amount of added Bi number by sintering promoting diffusion barrier2 O3 In the case of less than 2%, less than 3% in the case of glass number valve timing of the other. Magnetic layer (251) number 2 a sheet (215) is formed on the central portion of the top portion, such as also 11, number 1 sheet (216), a coil (241) is formed a plurality of number 2 sheet (215) and number 1 sheet (216) are sequentially formed on a laminate (210) by a plurality of disclosed. Such urging the stack (210) such as returning to close to each other. Then, such as 12 also, if ZnO NiO and including pressurized can take place after it is heated at a temperature predetermined magnetic layer (251) is equal to a peripheral diffusion. The, magnetic layer (251) and in contact with the number 2 sheet (215) by a portion of said number 1 mutual diffusion sheet (216) very similar properties to permit diffusion (250) to form with each other. At this time, even thought it does not also 12 is shown, coil (240) is arranged on the outside of the annular track on plane view rotates at the number 2 sheet (215) to be coated is still non-magnetic properties. The, disposed externally of the annular track the number 2 sheet (215) in gap (Gap) shall take on the role of the chip inductor.
