PROBLEM TO BE SOLVED: To plate a specified region easily, effectively and firmly by irradiating a polymer formed article obtained by adding a galss filler and an inorg. filler such as a ceramic grain to a polymer material with a laser beam of specified wavelength, fluence and input energy. SOLUTION: An inorg. filler is added to a polymer material such as liq.- crystal polymer, polyether sulfone, polybutylene terephthalate, polycarbonate, polyimide and epoxy resin, and the obtained polymer parts are irradiated with a laser beam. The laser beam has <=600 nm wavelength and 0.1-0.51 J/cm2/pulse fluence, the total input energy is 10-500 J/cm2, and the fluence and the number of irradiations are preferably so controlled that the irradiated region has an electrical conductivity suitable for electroplating. Besides, a glass filler, a ceramic grain or the like are used as the inorg. filler, and the addition is preferably controlled to 10-50 wt.%. Consequently, the scattering region of the debris of laser beam irradiation is limited, and the region to be plated is made electrically conductive.
