A method for cold-forging a thin-walled portion by which a thin-walled portion having a set thickness is formed directly from a metal base plate having a sufficiently large thickness and an explosion-proof valve are provided. Blade side surfaces of upper and lower dies for shearing the metal base plate are set in an overlapping manner with a predetermined clearance δ therebetween. Sheared surfaces are formed with the blade side surfaces of the upper and lower dies in the metal base plate along a processing direction while leaving the set thickness t2 therebetween and the metal base plate is compressed by the overlapped portions until work-hardened to form the thin-walled portion with the horizontal width δ and the set thickness t2 between the sheared surfaces. The formation of the sheared surfaces eliminates a need to press portions of the metal base plate positioned at both the sides of the thin-walled portion into both the sides during the processing of the thin-walled portion and the thin-walled portion can thus be formed at a high compression processing rate with a smaller processing load.
