Layered product

A layered product in which a metal layer is layered on a roughened surface of a molded article obtained by molding a polyarylene sulfide resin composition, wherein:

• the polyarylene sulfide resin composition is obtained by blending a polyarylene sulfide resin (A), a thermoplastic resin (B) other than a 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-based wax (D);
• the carbonate (C) is a particulate substance having an average particle diameter of 0.3 μm or more and 1.2 μm or less;
• the thermoplastic elastomer (b1) is at least one selected from the group consisting of a polyolefin-based thermoplastic elastomer, a fluorine-based thermoplastic elastomer, a silicone-based thermoplastic elastomer, a styrene-based thermoplastic elastomer, a fluorine resin-based thermoplastic elastomer, and a urethane resin-based thermoplastic elastomer;
• the hydrolyzable thermoplastic resin (b2) is at least one resin having a resin structure selected from the group consisting of a polyamide resin, a polyester resin, a polycarbonate resin, a polyether resin, a polyurethane resin, a polyketone resin, a polylactone resin, a polyacetal resin, a polyimide resin, a polyamideimide resin, a polyarylate resin, a polyetherimide resin, a polyether ether ketone resin, a thermoplastic epoxy resin, and a thermoplastic phenolic resin, or a copolymer having said resin structure;
• and
• the roughened surface of the molded article is roughened by chemical etching treatment.
