Abstract: PURPOSE:To prevent generation of racks in an abrasion-resistant layer by providing a resin protecting layer consisting of an uppermost layer and a lowermost layer, both being formed using an amorphous silicon carbide. CONSTITUTION:A heat-resistant insulating substrate consists of a resin protecting layer 3, a heat-resistant resin layer 2 and a metal substrate 1, and the resin protecting layer 3 is formed on the heat-resistant layer 2. The resin protecting layer 3 consists of an amorphous silicon oxide based on silicon containing at least, either of hydrogen or halogen and an amorphous silicon layer based on silicon containing at least, either of hydrogen or halogen. That is, the resin protecting layer is composed of a film consisting mainly of amorphous a-SiO as the amorphous cilicon oxide layer and a film consisting mainly of a-SiC as the amorphous silicon carbide layer. In addition, both the uppermost layer and the lowermost layer of these laminated layers are composed of the amorphous silicon carbide layer. Thus the thickness of the film of the entire resin protecting layer 3 is set to a specified value by laminating the a-SiO and the a-SiC which have a high film growth rate. Subsequently, the heat is prevented from migrating from the thermal resistor to the metal substrate 1.
