Abstract

A Peltier element is provided so that an electrically conductive plate forming a heat absorbing portion is in close proximity to an insulating layer and an electrically conductive plate forming a heat radiating portion is provided in close proximity to an insulating layer. The Peltier element has one end connected to a branch line branched from a power line, and has the other end electrically connected to an electrode plate. Further, the Peltier element receives from the branch line a portion of electric power supplied to a power transistor, and outputs it to the electrode plate. In other words, the Peltier element uses the portion of the electric power supplied to the power transistor, to absorb heat generated by the power transistor and radiate it toward a heat radiating plate.
