PROBLEM TO BE SOLVED: To provide a specific resin composition or the like for electric insulation excellent in thermal resistance, low thermal expansion property, insulation, and adhesion which, moreover, can produce a hybrid cured matter without fear of void, crack, or the like, and facilitate molding process in a semi-cured state. SOLUTION: The resin composition for electric insulation contains methoxy- group-containing silane-denatured novolac type epoxy resin obtained by demethanolic condensation reaction of oxyepoxy resin obtained by denaturation with ring opening of a part of epoxy group of novolac type epoxy resin (1) and methoxysilane partial condensation matter (2). Or, one containing methoxy- group-containing silane-denatured novolac type epoxy resin obtained by demethanolic condensation reaction of oxyepoxy resin obtained by denaturing a part of epoxy group of novolac type epoxy resin (1), a partial methoxysilane condensation product (2) and an epoxy compound having one hydroxy group in one molecule (3). |
