The present invention relates to an epoxy group-containing silicon compound which is obtained by condensing at least one epoxy group-containing alkoxy silicon compound per se represented by the general formula (1a): R<SUB>1a</SUB>Si(OR<SUB>2</SUB>)<SUB>3</SUB>, wherein R<SUB>1a </SUB>denotes a substituent having an epoxy group and R<SUB>2 </SUB>denotes an alkyl group having at most 4 carbons, or said compound and at least one substituted alkoxy silicon compound represented by the general formula (1b): R<SUB>1b</SUB>Si(OR<SUB>3</SUB>)<SUB>3</SUB>, wherein R<SUB>1b </SUB>denotes an alkyl group having at most 10 carbons, an aryl group or an unsaturated aliphatic residue and R<SUB>3 </SUB>denotes an alkyl group having at most 4 carbons, in the presence of a basic catalyst.
