摘要:
A thick film circuit board that can be produced at a low cost, a method of producing the same, and an integrated circuit device. A first thick film circuit board has conducting layers of a copper-containing conductor fired at not higher than 750° C., and includes conducting portions formed by using a silver-containing conductor. A second thick film circuit board has conductors that are formed in the through holes so as to close the openings of at least the one side thereof. The thick film circuit board is produced at a low cost and suppresses a drop in electric conductivity when it is in use.
