The present invention provides a laminated body including a support (A) that includes a polyphenylene sulfide resin composition containing a polyphenylene sulfide (a1) and an elastomer (a2), and a metal layer (B) and a metal-plating layer (C) that are laminated on the support (A) in this order, wherein the elastomer (a2) is contained in the polyphenylene sulfide resin composition in an amount in the range of 0.3 to 90 parts by mass relative to 100 parts by mass of the polyphenylene sulfide (a1). The laminated body is excellent in adhesiveness between the polyphenylene sulfide as the support and the metal-plating layer, and also has a thermal resistance so as to maintain the excellent adhesiveness even when exposed to a high-temperature environment.
