The present invention relates to embossed wallpaper having a multilayer foaming layer formed thereon. A PVC foaming resin, a plasticizer, a stabilizer, a foaming agent, a viscosity adjusting agent, and a filler are combined, and PVC plastic sol is foamed, so a first foaming layer is formed on the surface of wallpaper raw paper. A PVC foaming resin, a plasticizer, a stabilizer, a foaming agent, a viscosity adjusting agent, and a filler are combined on the surface thereof, and PVC plastic sol is dried or foamed, so a second foaming layer is produced. A conventional product embossed by a chemical embossing process has disadvantages due to pattern expression thereof. The disadvantages are that the applicability of wallpaper is reduced due to relative heaviness of the weight of the product and that a wallpaper surface is seen due to a relatively thin product thickness. To this end, first and second foaming layers having different diameters are formed, so the weight of wallpaper is made to be ...
