The plurality of coolers is laminated with the power cards. The cooler includes a body, a gasket and a metal plate. The body is made of resin, and has an opening that is provided in a side surface of the cooler that faces the adjacent power card. A surface on one side of the metal plate is configured to close the opening through the gasket, and the other surface faces the power card. The pressure member is configured to apply a pressure in a laminating direction on a lamination unit. The opening is sealed by the metal plate by pressure applied by the pressure member on the lamination unit.
