ABSTRACT:
An electronic circuit device including a heat-generating element is mounted on a circuit board composed of three laminated layers: a heat-receiving layer on which the heat-generating element is mounted, an insulating layer, and a heat-dissipating layer. The heat-receiving layer is connected to the heat-dissipating layer through heat-conductive passages formed in the insulating layer. The heat generated in the heat-generating element is transferred to the heat-dissipating layer through the heat-conductive passages, and the heat is efficiently dissipated on both the heat-receiving layer and the heat-dissipating layer.
