<p>PROBLEM TO BE SOLVED: To provide a small hybrid module with good heat-radiation and high reliability. SOLUTION: A heat-radiation internal electrode 17a wherein, connected to a ground terminal of a circuit part 13 having heat-accumulation characteristics which is mounted in a recessed part 14 formed at a circuit board 11, a part is exposed outside the surface of the circuit board 11 is formed, and the internal electrode 17A is connected to a heat-radiation external electrode 17C, etc., through a thermal via hole 17B. The heat generated at the circuit part 13 is transferred to the heat-radiation internal electrode 17A through an insulating resin 16, and then radiated to the outside space from the exposed part of the internal electrode 17A and the external electrode 17C.</p> |
