To secure high distinguishability of a battery and furthermore to attain downsizing of the battery.SOLUTION: A battery comprises a casing and a terminal portion including a connection terminal connected to an electrode terminal of connection equipment. A functional groove of which the length direction matches with a connection direction of the connection terminal and the electrode terminal and which has a predetermined function, a stepped surface continuous with a side surface of the casing and a groove forming surface which is continuous with a bottom surface of the casing and in which a guided groove is formed are formed in the casing. A notch is formed from the stepped surface and the groove forming surface. Out of the surfaces forming the functional groove, a surface positioned closest to a top surface side is positioned closer to the bottom surface side than a terminal edge of the guided groove which is positioned closest to the top surface side.SELECTED DRAWING: Figure 4
