PURPOSE: A power module is provided to supply the power module with a superior heat radiation property. CONSTITUTION: A conductive circuit is formed on an insulating layer(5) in a substrate(2) for a power module(1). A power device(3) is installed on the substrate for the power module and electrically connected to the conductive circuit. A thermally conductive sheet radiates heat generated from the power device and/or the substrate for the power module. The thermally conductive sheet includes a plate shaped boron nitride particle. The thermal conductivity in the orthogonal direction with respect to the thickness direction of the thermally conductive sheet is more than or equals to 4 W/m·K. |
