PURPOSE: To manufacture an electromagnetic wave shield of a highly processed layer having high corrosion resistance and stable electromagnetic wave shielding characteristics by providing thermoplastic synthetic resin layers at both sides of a conductive composition layer made of carbon fiber, metal fiber and thermoplastic synthetic resin.
CONSTITUTION: When thermoplastic synthetic resin 3 is formed as a single sheet by a heating roll, a conductive composition layer 2 is interposed between the sheets 3 and contact pressed by the roll or a hot press or the resin 3 is sheeted by the roll, the layer 2 is interposed between both the surface layers, simultaneously sheeted to simultaneously obtain a laminated composite sheet 1. The sheet 1 can be used as an electromagnetic wave shield to be bonded to a wall surface or a floor surfaces as it is. Or, an electromagnetic wave shield having a box state or other various shape such as a housing for an electronic apparatus or a shielded case for an electronic apparatus can be simultaneously molded by heat molding means such as a hot press, a vacuum molding, etc.
