The power card disclod in this specification includes a miconductor element, a heat transfer plate and a resin package, and is aled in a resin package with a miconductor element fixed to the heat transfer plate, and a part of the
heat transfer plate is expod to the surface of the resin package.In the expod surface of the heat transfer plate, a groove extending in the arcuate shape of the expod surface is formed, and the grooves are distributed over the entire expod surface.Each groove intercts the other grooves (which also extend arcuately on the expod surface).By adopting the power card, the polishing marks can be ud in the grooves which affect the movement of the grea.That is, the grea can be prevented from being blown out and the number of steps can be reduced without increasing the number of steps.Diagram
