Abstract:
1. A circuit-connecting material for interposing between circuit electrodes facing each other and electrically connecting the electrodes, after curing by heat and pressure, either by direct contact or via conductive particles present in the material, wherein the circuit-connecting material comprises: (1) a curing agent capable of generating free radicals upon heating; (2) a hydroxyl-group-containing resin, wherein the hydroxyl-group-containing resin is a phenol resin; and (3) a radical-polymerizable substance, wherein the circuit-connecting material includes two or more layers, wherein a first layer contains conductive particles and a second layer contains the curing agent.
