An electronic unit includes a double-sided substrate having an insulation substrate, a patterned first metal plate bonded on one side of the insulation substrate, and a patterned second metal plate bonded on the other side of the insulation substrate, and also includes a heat radiation member for releasing heat from the double-sided substrate. The heat radiation member is disposed adjacent to one of the first metal plate and the second metal plate generating a larger amount of heat than the other of the first metal plate and the second metal plate.
