The cooling fins have a shaft part and vane parts that protrude outward from the shaft part and extend spirally in the axial direction; the overall cooling fin configuration constituting a quadrangular column shape. The cooling fins are disposed in contact with at least the top plate and the bottom plate, and the flow path has a spiral-formed configuration formed by the vane parts, the top plate, and the bottom plate.
