<p>PROBLEM TO BE SOLVED: To provide a method for forming a fine metal pattern capable of corresponding to even an electric circuit by electroless plating while using a general-purpose resin material without increasing a manufacturing cost.SOLUTION: A method for forming a pattern 10 formed by metal-plating (10c-10e) a surface 2 of a resin molding 1 comprises: a foam roughening step s2 of irradiating the surface of the resin molding with a laser beam so as to draw the pattern to form a portion irradiated by the laser beam in the resin molding into a porous state; a plating coating material application step s3 of selectively applying a plating coating material to the portion formed into a porous state; and a plating step (s6-s8) of forming a metal plating layer having one or more layers in the portion formed into a porous state and applied with the plating coating material by electroless plating.</p> |
