PROBLEM TO BE SOLVED: To form a metallic film on a resin substrate with good adhesion by carrying photocatalyst particles which degrade the resin of the resin substrate on the surface of the resin substrate, irradiating the photocatalyst particles with UV, removing these by washing in water under ultrasonic vibration and coating the resin substrate with metal by sputtering, vacuum deposition or electroless plating. SOLUTION: The resin of the resin substrate is degraded by the action of the photocatalyst to roughen the surface of the substrate. Then the washing in water under ultrasonic vibration is carried out, the photocatalyst particles remaining on the surface of the substrate are removed by the cavitation action of ultrasonic waves. The photocatalyst particles are preferably dispersed in a water-soluble medium, applied and carried on the surface of the resin substrate. The photocatalyst is preferably anatase type titanium dioxide and the irradiation with UV is preferably carried out by exposure to plasma. The resin of the resin substrate may be acrylic resin, polyethylene or epoxy resin.
