Abstract: In a battery frame, an upper panel is made of carbon fiber reinforced plastic, and first reinforcements are made of sheet metal. Head portions of rivets are disposed at the upper panel side, and a diameter dimension of the head portions is set larger than that of caulking portions of the rivets. This enables a contact surface area between the rivets and the upper panel to be larger than in cases in which the caulking portions are disposed at the upper panel side. This enables peripheral edge portions of first joint holes in the upper panel to be supported by the head portions of the rivets over a large surface area. The peripheral edge portions of the first joint holes in the upper panel are thereby suppressed from breaking and the like.
