摘要

A method for roughening the surface of a resin molded article to make it susceptible to metallizing is disclosed, comprising contacting a resin molded article at least the surface portion of which to be roughened mainly comprises a block copolymer comprising 100 parts by weight of a polyarylene sulfide component block and from 100 to 200 parts by weight of a polyarylene sulfide ketone component block with a solvent capable of dissolving a polyarylene sulfide ketone more than a polyarylene sulfide.
