摘要： This arc spot welding method for dissimilar materials joins a steel upper plate and a non-ferrous metal lower plate. The upper plate has a flat plate-like base part and an upright wall part erected on the base part. The base part has a through-hole. The arc spot welding method for dissimilar materials includes superposing the base part on the lower plate so that the lower plate faces the base part via the through-hole; and arc-welding the base part and the lower plate by filling the through-hole with a molten weld metal at a position, which is a target position, offset in the direction opposite the upright wall part from the center of the through-hole.

摘要： A battery case, including a cross member between a pair of opposing wall surfaces of an inner peripheral surface of a rectangular frame body to partition an inside space surrounded by a frame body, and a bonding assistance member between each end portion of the cross member and each of the wall surfaces of the frame body facing the end portion. One end portion of the bonding assistance member is welded to the wall surface, and the bonding assistance member has an overlap portion extending from the one end portion toward the inside space and overlapping with a side surface of the end portion of the cross member.
