- a chassis with which the first main surface of the battery cell comes into contact;
- and
- a holding plate that includes:
- a strip-like portion that covers a central portion of the second main surface of the battery cell in a band, in an area facing the second main surface of the battery cell;
- a relief portion on a surface between the second main surface and a side surface of the battery cell, the relief portion being configured such that the holding plate does not make contact at the relief portion;
- and
- a step portion between the strip-like portion and the relief portion such that the relief portion is formed from the step portion toward an area facing the side surface of the battery cell, wherein
- when the holding plate presses against the battery cell, the holding plate comes into contact with the second main surface of the battery cell at an edge of the step portion.
