To solve the problems that there often occur shrinkage of a decoration sheet, exposure of a substrate caused by peeling etc., occurrence of creases at a rising portion etc., and a warping of the whole, which are caused when producing a housing by decorating the surfaces of the housing by pasting by means of vacuum molding or vacuum pressure molding the decorating sheet such as a skin type having a fiber layer on the surface of a coated molding made of a metal etc. which is a material of the housing used for an electronic device.
The problems can be dissolved by pasting by means of vacuum molding or vacuum pressure molding the decorating sheet formed with a shrinkage suppressing adhesive layer coated and impregnated with a thermoplastic adhesive based on a synthetic rubber containing glass minute particles on a surface region one side of the fiber layer wherein a foamable resin layer and a non-foamable resin layer are laminated in this order in the other surface side of the fiber layer.
