Patent ID: 8901207

Claim:
An adhesive for electronic components, comprising: an epoxy compound having an aliphatic polyether backbone and a glycidyl ether group; an epoxy group-containing acrylic polymer; an episulfide compound; and a curing agent, wherein the epoxy compound having an aliphatic polyether backbone and a glycidyl ether group has a number-average molecular weight of 800 to 10000, wherein the epoxy group-containing acrylic polymer has an epoxy equivalent of 300 to 1000 and a number-average molecular weight of 5000 to 50000, wherein the amount of the episulfide compound is 1 part by weight or more, and less than 30 parts by weight, relative to 100 parts by weight of the epoxy compound having an aliphatic polyether backbone and a glycidyl ether group, wherein the amount of the epoxy group-containing acrylic polymer is 4 part by weight or more, and less than 40 parts by weight, relative to 100 parts by weight of the epoxy compound having an aliphatic polyether backbone and a glycidyl ether group, and further comprising 1 to 20 parts by weight of an epoxy compound having an aromatic skeleton and a number-average molecular weight of 150 to 500, relative to 100 parts by weight of the epoxy compound having an aliphatic polyether backbone and a glycidyl ether group.
