PROBLEM TO BE SOLVED: To effectively address an internal short circuit of a power generation element in a battery.SOLUTION: In a battery including a power generation element 3 that has a foil shaped positive electrode plate 22 and a foil shaped negative electrode plate 23 arranged with a separator therebetween, a contour in corner 23d of the foil shaped positive electrode plate 22 or the foil shaped negative electrode plate 23 is located nearer the inside than a virtual contour F obtained by crossing two extended liner lines forming the corner. Therefore, the pull-in of the corner 23d due to pressing force of a foreign material, etc. is suppressed. |
