Abstract
A power module includes a power module board including an insulating layer and a conductive circuit formed on the insulating layer, a power device provided on the power module board and electrically connected to the conductive circuit, and a thermal conductive sheet for dissipating the heat generated from the power module board and/or the power device. The thermal conductive sheet contains a plate-like boron nitride particle and the thermal conductivity in a direction perpendicular to the thickness direction of the thermal conductive sheet is 4 W/m·K or more.
