PROBLEM TO BE SOLVED: To provide a conductive glazed insulator for discrimination, capable of discriminating the insulator within the same categories or from the others, without causing the insulator property to be deteriorated. SOLUTION: The conductive glazed insulator 1 for discrimination is composed of the conductive glazed layer 3 and the conductive glazed layer 4, that consists of the insulating glazer different in color from the conductive glazer formed on a part of the conductive glazed layer 3, or preferably on the most external portion of the cover 1a.
