In a battery frame (10), an upper panel (18) is made of carbon fiber reinforced plastic, and first reinforcements (14) are made of sheet metal. Head portions (44) of rivets (40) are disposed at the upper panel (18) side, and a diameter dimension of the head portions (44) is set larger than that of caulking portions (46) of the rivets (40). This enables a contact surface area between the rivets (40) and the upper panel (18) to be larger than in cases in which the caulking portions (46) are disposed at the upper panel (18) side. This enables peripheral edge portions of first joint holes (34) in the upper panel (18) to be supported by the head portions (44) of the rivets (40) over a large surface area. The peripheral edge portions of the first joint holes (34) in the upper panel (18) are thereby suppressed from breaking and the like.
