Abstract

See full text

According to the present invention, a heat-dissipating circuit board is formed by providing a metal material adjacent to one surface of an insulating layer and providing a conductive metal layer to the other surface of the insulating layer. The metal material is a sheet of copper or a copper alloy or aluminum or an aluminum alloy and is 0.2-20 mm thick. The insulating layer is a metal oxide layer that has the composition AlxOyTz, is 0.2-30 μm thick, has a volume resistivity of at least 1000 GΩ·cm, and has a porosity of no more than 10%. The heat-dissipating circuit board has excellent heat-dissipation properties and insulation properties.
