    摘要: Provided is a method for manufacturing an electromagnetic wave-shielding member that is a laminated body having a plating layer that can be formed on a surface of a polyarylene sulfide (PAS) molded product by a simple step through high adhesive strength and has excellent electric field shielding properties and magnetic field shielding properties. More particularly, provided are an electromagnetic wave-shielding member and a method for manufacturing the electromagnetic wave-shielding member that is a laminated body including a step of roughening a surface of a molded product obtained by molding a PAS resin composition by a chemical etching treatment, and a step of subjecting the roughened surface of the molded product to a plating treatment, wherein the laminated body has a plating layer on at least two surfaces that are paired, and the PAS resin composition is obtained by mixing a PAS resin (A), a thermoplastic resin (B) other than the polyarylene sulfide resin selected from the group consisting of a thermoplastic elastomer (b1) and a hydrolyzable thermoplastic resin (b2), a carbonate (C), and a polyolefin wax (D).
