A method of resin plating using an etching bath comprising manganese as an effective component provides a method capable of maintaining a stable etching performance even in continuous use. A method of resin plating comprising an etching step using an acid etching bath containing manganese, a catalyst applying step using palladium as a catalyst metal, and an electroless plating step using an article containing a resin material as an object to be treated, Further comprising the step of maintaining the palladium concentration in the acid etching bath at 100 mg / L or less. |
