Title: BATTERY AND CONNECTION DEVICE
Abstract:
The present invention reduces the size of a battery while ensuring high identifiability. The present invention includes: a casing that has a cell accommodated therein; and a terminal portion that has a connection terminal connected to an electrode terminal of a connection device. A functional groove having a prescribed function is formed in the casing such that the length direction thereof matches the direction in which the connection terminal and the electrode terminal connect together. The functional groove is formed by linking, in a continuous manner, a plurality of functional portions having different lengths. There is thus no section for partitioning functional portions between the plurality of functional portions having different lengths, and therefore the size of the functional groove in the direction in which the functional portions are linked corresponds to the total size of the plurality of functional portions. Consequently, it is possible to achieve a battery that is reduced in size while ensuring high functionality.
