PROBLEM TO BE SOLVED: To provide a method of producing an electromagnetic wave shield casing where infiltration of water from external environment is prevented surely. SOLUTION: In a first molding process, the back surface of an insertion material 4 is supported by a surface 108 formed by a metallic mold 10B. Thus, when resin for first molding is poured into the recess 100 of a metallic mold 10A, the insertion material 4 is never deformed. By first molding, an outer wall 6 having a projecting part 6a projecting on the side of an inner wall and a cavity 6b opposing a through hole 41a is formed. In a second molding process, when resin for second molding is poured into the recess 104 of a metallic mold 11B, the resin flows into the cavity 6b from the through hole 41a. Since the insertion material 4 is supported by the outer wall 6 in the case of second molding, the insertion material 4 is never deformed due to pouring of the resin. COPYRIGHT: (C)2005,JPO&NCIPI
