<P>PROBLEM TO BE SOLVED: To provide an electromagnetic-wave shielding composite material having light weight, a good electromagnetic-wave shielding characteristic, and high rigidity, an electronic device housing and a battery case that are made of an electromagnetic shielding material formed of the electromagnetic-wave shielding composite material. <P>SOLUTION: The electromagnetic-wave shielding composite material is formed by stacking a fiber-reinforced resin molding part containing carbon fiber and matrix fiber, and a metal layer part. The fiber-reinforced resin molding part contains 20 to 80 weight percent of carbon fiber having a weight average fiber length of 0.5 to 100 mm in random dispersion state. The metal layer part has a thickness of 0.02 to 2 mm. The electromagnetic-wave shielding composite material may have a sandwiched lamination structure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
