(57) [Summary] [PROBLEMS] To increase the peeling strength of a plating film in plating a thermoplastic resin molded product, to provide a large molded product and excellent heat resistance, and to withstand vibration, thermal shock, and long-term use. Kind Code: A1 A metal has a structure in which metal is continuously entangled inside a base resin near an interface with a metal plating layer. In other words, the plating metal enters a continuous hole formed inside the resin surface. It is a metal-plated resin molded product forming a mutual network structure. By controlling the particle size and content of the acid-soluble inorganic filler to be mixed with the polypropylene and the etching conditions, a plating film peeling strength of 2 kg / cm or more is developed. |
