Title: RESIN COMPOSITION, INSULATING MEMBER, AND IGNITION COIL FOR INTERNAL COMBUSTION ENGINE
Abstract:
The present invention improves the insulating properties of a resin composition constituting part of an insulating member, and corresponds to an increase in output of an ignition coil for an internal combustion engine. A resin composition according to the present invention comprises an epoxy resin and an acid anhydride, and the acid anhydride content is 0.5 to 0.8 in terms of the equivalence ratio defined below. Equivalence ratio = (added amount of acid anhydride (g)/acid anhydride equivalents (g/eq))/(added amount of epoxy resin (g)/epoxy equivalents (g/eq))
