Abstract
A reliable power module is realized, in which a good performance of radiating heat of the power semiconductor element is secured and it is hard for the heat of a power semiconductor element to be conducted to a driving element. A power module includes a power semiconductor element mounted on a lead frame, and a driving element mounted on the lead frame, and a heat radiating plate radiating heat which is generated by the power semiconductor element, and a resin holding the power semiconductor element, the driving element, and the heat radiating plate, wherein the heat radiating plate has a portion disposed at a side opposite to a surface of the lead frame where the power semiconductor element is mounted, a portion disposed between the power semiconductor element and the driving element, and a portion disposed below the power semiconductor element, as the portions being in a body.
