Abstract: A treatment device has: a treatment tank provided with a constant temperature heater on the outer periphery; an electrolytic cell continuing from a pipe provided with a circulation pump; and a pipe for supply to the treatment tank from the electrolytic cell. Within the electrolytic cell are provided an anode and a cathode formed from diamond electrodes and a bipolar electrode disposed between the two. The treatment tank and the electrolytic cell are filled with a prescribed concentration of sulfuric acid. The treatment device is configured such that a persulfate solution such as peroxydisulfuric acid is generated by electrolysis of the sulfuric acid by making a prescribed current flow from a direct current power supply unit to the anode and the cathode, and this persulfate solution can be supplied to the treatment tank via the pipe.

Abstract: A novel technique that is a resin etching technique without using chromic acid and can be operated at an industrial level is provided by a resin surface etching method characterized in that, in etching a resin surface, one set of the following steps (a) and (b) is performed two or more times without performing a resin swelling step: (a) a step of treating the resin surface with a solution containing an oxidizing agent and adsorbing the oxidizing agent on the resin surface, and (b) a step of activating the oxidizing agent adsorbed on the resin surface in the step (a).

Abstract: An object of the present invention is to provide a plating tool which avoids plating deposition on the tool itself in plating of a resin molded body, and therefore, also eliminates the need to exchange the plating tool. The object is achieved by a tool for plating a resin molded body, wherein a surface of a plating tool having an insulation coating part is coated with a plasticizer, and a method for plating a resin molded body using the tool.
