<P>PROBLEM TO BE SOLVED: To provide a method for swiftly making a pattern with a metallic appearance on a housing. <P>SOLUTION: The method comprises: a step where a substrate is provided; a step where a metal film is formed on the surface of the substrate; a step where the metal film and the substrate located at the lower part of the metal film are heated and bonded; and a step where, in the metal film, the region not heated and bonded in the substrate is removed. In the heating-bonding step, a laser light source is outputted, and a laser beam from the laser light source is irradiated, thus the substrate and the metal film are heated and bonded, and in the removing step, the region not irradiated by the laser is removed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
