Abstract:
1. A circuit terminal connected structure comprising a first circuit member having a first connecting terminal and a second circuit member having a second connecting terminal, wherein the first circuit member and the second circuit member are disposed so that the first connecting terminal and the second connecting terminal face each other, and a circuit-connecting material capable of curing upon radical polymerization is interposed between the first connecting terminal and the second connecting terminal which face each other, and a surface of at least one of the first connecting terminal and the second connecting terminal is formed of a metal selected from the group consisting of gold, silver, tin and platinum group metals, and the first connecting terminal and the second connecting terminal that face each other are electrically connected; and the circuit-connecting material capable of curing upon radical polymerization comprises, as essential components, the following components (1) to (4): (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; (2) a first radical-polymerizable substance comprising a maleimide compound having at least two maleimide groups in a molecule; (3) a second radical-polymerizable substance comprising acrylates or methacrylates; and (4) conductive particles.
