A method for producing a plated part, includes: forming, on a surface of a base member, a catalyst activity inhibiting layer containing a polymer which has at least one of an amide group and an amino group; irradiating with light or heating a part of the surface of the base member on which the catalyst activity inhibiting layer is formed; applying an electroless plating catalyst to the surface of the base member heated or irradiated with the light; and bringing an electroless plating solution into contact with the surface of the base member to which the electroless plating catalyst is applied, to form an electroless plating film at a light-irradiated portion or a heated portion of the surface.
