Patent ID: 7785708

Claim:
A temporary circuit connection structure before curing process, comprising: at least one of a first circuit member having a first circuit electrode; a second circuit member having a flexible substrate and a second circuit electrode; and a circuit connection member including an uncured adhesive film for circuit connection comprising: a curing agent to generate free radicals with heating; radically polymerizable substances including (a) urethane acrylate and/or urethane methacrylate having a viscosity at 25° C. in a range of 100,000 mPa·s to 1,000,000 mPa·s, and (b) acrylate and/or methacrylate having dicyclopentenyl group and/or tricyclodecanyl group; and a film-forming polymer, wherein a temporary fixing power of said uncured adhesive film to the flexible substrate having the circuit electrode is 40-180 N/m.
