Abstract
An epoxy resin composition containing an epoxy resin and a thermal cationic polymerization initiator not only can reduce the amount of fluorine ions generated during thermal cationic polymerization to improve electrolytic corrosion resistance but also is excellent in low-temperature rapid curability. The epoxy resin composition uses a sulfonium borate complex represented by the formula (1) as the thermal cationic polymerization initiator. In the formula (1), Ris an aralkyl group, and Ris a lower alkyl group, provided that when Ris a methyl group, Ris not a benzyl group. X is a halogen atom, and n is an integer of 1 to 3.
