(canceled)
A battery to hold a battery cell, the battery comprising:
- a first surface;
- an end surface approximately perpendicular to the first surface and forming a corner edge with the first surface along an edge of the first surface in a lateral direction;
- an output terminal provided at the corner edge formed by the end surface and the first surface, the output terminal including electrode slits that are opened to both the end surface and the first surface, and the electrode slits including electrodes to output power from the battery cell;
- first and second grooves provided in the first surface that extend away from the corner edge along the first surface, the output terminal being provided between the first and second grooves in the lateral direction;
- and
- first and second cut out portions that extend in a longitudinal direction along respective first and second lateral sides, at least a part of surfaces of the first and second cut out portions being tilted with respect to the first surface.
