The coating layer includes a rubber layer and a lubricating layer having a lower coefficient of friction than the surface of the metal plate portion. In the coating layer on a part of the surface of the metal plate portion that includes at least a periphery of the sealing target hole, the rubber layer and the lubricating layer are laminated and the lubricating layer is arranged on a surface layer of the coating layer. In the coating layer on a periphery of the fastening hole, the rubber layer is laminated and the rubber layer is arranged on a surface layer of the coating layer.
