To provide a manufacturing method of an electronic device cabinet which does not degrade radio communication performance while maintaining radio wave interception performance and is superior particularly in design characteristics.
A production process of fiber reinforced plastic cabinet for electronic device forms a platy molding precursor by arranging following molding material base (A) and molding material base (B) in a way the molding material base (B) may be inserted through thickness direction; heating the molding precursor to a temperature higher than melting temperature of any thermoplastic resin in the molding material bases and then forms a fiber reinforced plastic molding by press molding at a temperature lower than melting temperature of any thermoplastic resin in the molding material bases. The molding material base (A) contains a conductive fiber as its reinforcement fiber and a thermoplastic resin as its matrix. The molding material base (B) contains an insulating fiber as its reinforcement fiber and a thermoplastic resin as its matrix. A region formed by the molding material base (A) makes a radio wave shielding region 1a since it has a high radio wave interception performance and a region formed by the molding material base (B) makes a radio wave transmission region 1b since it has a low radio wave interception performance.
