Patent ID: 7604868

Claim:
An electronic circuit comprising: (a) a first circuit member having a first electrode; (b) a second circuit member having a second electrode disposed to face the first electrode; and (c) a circuit-connecting material interposed between the first electrode and the second electrode that, after curing by heat and pressure, electrically connects the first electrode to the second electrode by direct contact, wherein the circuit-connecting material, before curing by heat and pressure, comprises: (1) a curing agent capable of generating free radicals upon heating, wherein the curing agent has a 10-hour half-life temperature of 40° C. or above and a 1-minute half-life temperature of 180° C. or below, and the curing agent comprises peroxyester; (2) a radical-polymerizable substance; and (3) a hydroxyl-group-containing resin having a weight-average molecular weight of 10,000 or more, wherein the hydroxyl-group-containing resin is at least one of polyvinyl butyral, polyvinyl formal, polyamide polyester, phenol resin, epoxy resin and phenoxy resin.
