Application of circuit-connecting material as circuit-connecting material

The invention provides the application of a circuit-connecting material as a circuit-connecting material. The circuit-connecting material of the invention is a circuit-connecting material for connection between a first circuit member having a first circuit electrode formed on the main side of a first board, and a second circuit member having a second circuit electrode formed on the main side of a second board, with the first circuit electrode and the second circuit electrode laid facing each other. The connecting material contains the specific components. The connecting material in the application exhibits especially satisfactory bonding strength for circuit members wherein the board supporting the circuit terminals is composed of at least one selected from among organic insulating materials and glass, and circuit members whose surfaces have been treated with at least one selected from among silicon nitride, silicone resins and polyimide resins, and which has a sufficient usable life.
