The present invention is a process of producing a plating resin molded article, wherein
metal plating is carried out on the surface of a
thermoplastic resin molded article and either of requirements (1), (2) and (3) described below is included: (1) the
thermoplastic resin molded article contains a
thermoplastic resin and a water-soluble substance, a step of carrying out the removal of fat of the resin molded article and a step of
electroless plating are provided in combination, and a step of
etching by an acid containing a heavy
metal is not included; (2) the thermoplastic resin molded article contains a
polyamide-based resin and a
styrene-based resin, a step of carrying out the removal of fat of the resin molded article and a step of
electroless plating are provided in combination, and a step of
etching by an acid containing a heavy
metal is not included; or (3) a step of contact-treating the thermoplastic resin molded article with an acid or base not containing a heavy metal as the pre-treatment of the metal plating step is included. The present invention provides further the plating resin molded article obtained by the above-mentioned step. Although an
etching treatment by
chromic acid is not carried out, the plating resin molded article having a high adhering strength of a plating layer is provided.
