Abstract
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. The circuit-connecting material features the following essential components: (1) a curing agent capable of generating free radicals upon heating, (2) a phenoxy resin having a weight average molecular weight of 10,000 or more, and that is chemically modified by a carboxyl-group-containing elastomer, and (3) a radical-polymerizable substance.
