METAL MATERIAL AND MANUFACTURING METHOD THEREOF, AND CASE FOR ELECTRONIC EQUIPMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a metal material wherein a photocatalytic layer is less degraded, high catalytic performance is obtained, and a metallic taste of a substrate is maintained because of high transparency of the layer, and also to provide a manufacturing method thereof and a case for electronic equipment using the same.;SOLUTION: The metal material comprises a metal substrate, and a metal oxide film, composed of a metal oxide having photocatalytic action and substantially containing no impurity, on the surface of the metal substrate. The metal material preferably has a compound oxide produced by reacting the metal substrate with the metal oxide on the interface between the metal substrate and the metal oxide.;COPYRIGHT: (C)2010,JPO&INPIT
