Zusammenfassung:	PURPOSE:To obtain the titled composition which has excellent moisture resistance and gives a joining area with improved reliability, by mixing a polyepoxide with a specified amine compound. CONSTITUTION:A polyepoxide (e.g., diglycidyl ether of bisphenol A) is mixed with, as curing agent, an amine compound having in its molecule hydrogen atoms active on the epoxide (e.g., a modified amine of 4,4'- diaminodiphenylmethane type) in an amount to provide 0.6-0.9 equivalent of the active hydrogen atom of the amine per equivalent of the epoxide.
