Abstract
A metal film high in reflectivity and excellent in adhesion to a synthetic resin substrate even in the case where the metal film is sufficiently thin, is formed on a surface of the substrate by sputtering a metal target by ions through an inert gas plasma in a vacuum vessel, wherein the substrate is covered with an electrostatic shield during the sputtering.
