PROBLEM TO BE SOLVED: To provide electrodes for a battery device which can suppress uneven temperature distribution of the electrodes. SOLUTION: A battery is equipped with a collector (11) and a plurality of electrodes (12a) formed in a pattern on the surface of the collector (11). Among the electrodes for the battery device, the pattern formation density of electrodes in regions which has lower radiation than the other regions is lower than that of electrodes in the other regions.
