Abstract: A battery includes an electrode group, and a rectangular exterior casing that houses the electrode group and includes a tubular side wall, a bottom connected to a lower end of the side wall in a Z direction, and an opening provided at an upper end. An inner surface of the bottom of the exterior casing has a slope inclined with respect to a plane orthogonal to the Z direction. The electrode group is in thermal contact with the slope. The bottom may have a protrusion protruding inward in the Z direction of the exterior casing, and the slope may be formed on the protrusion.

Abstract: A battery module includes battery stacks, a first restraining part, and a plurality of second restraining parts. The first restraining part has: a flat plate part; a plurality of first wall parts that protrude from a main surface of the flat plate part, extend in a stacking direction of the batteries, and are arranged in a first direction; and second wall parts extending in the first direction at end parts of each wall part. The second restraining parts are disposed individually corresponding to the first wall parts and each have: a belt part extending parallel to the flat plate part; a third wall part protruding from the belt part toward the first wall part and extending in the stacking direction; and fourth wall parts extending in the first direction at end parts of the third wall part. There are arranged a plurality of housing spaces for the battery stacks.
