Claim 13:
14. The epoxy adhesive composition according to claim 1,
wherein the molecular weight of the modified polyvinyl acetal resin and the molecular weight of the adhesive layer modifier satisfy a ratio (molecular weight of modified polyvinyl acetal resin/molecular weight of adhesive layer modifier) of 20 to 7,500,
wherein the molecular weight of the modified polyvinyl acetal resin and the molecular weight of the adhesive layer modifier are calculated molecular weights, and the molecular weight of the modified polyvinyl acetal resin is calculated based on a degree of polymerization of the modified polyvinyl acetal resin, amount of each constitutional unit, and molecular weight of each constitutional unit.
