Abstract

Provided is a method for producing a laminate in which a substrate (A) comprising a resin composition containing polyphenylene sulfide (a1), a primer resin layer (B), a metal layer (C), and a metal plating layer (D) are sequentially stacked, wherein the method is characterized by comprising: a first step of applying a fluid material containing a primer resin to the surface of the substrate (A) by an immersion method to form a primer resin layer (B); a second step of applying a fluid material containing metal particles to the surface of the primer resin layer (B) by an immersion method to form a metal layer (C); and a third step of forming a metal plating layer (D) on the surface of the metal layer (C) by an electroplating method, an electroless plating method, or a combination thereof. By the method for producing a laminate, a metal film can be easily formed with high adhesion on the surface of polyphenylene sulfide, which is a hard-to-bond base material.
