Abstract: In the present invention, an electrode terminal of a battery includes: a first connection part that encloses one side in an axial direction of an annular groove portion provided in a circumferential wall of the battery; a second connection part that encloses another side in the axial direction of the groove portion; and a bridge portion that connects the first connection part and the second connection part. When the swelling of the battery causes the groove portion to expand in the axial direction, the bridge portion ruptures and thereby blocks a current flowing between the first connection part and the second connection part.
