PROBLEM TO BE SOLVED: To provide a size AA battery which can maintain safety and realize an increase in a battery volume, and can obtain a high capacity. SOLUTION: A power generating element (a cathode mixture 2, an anode mixture 3 or the like) is housed in a battery case 1 of a bottomed cylindrical shape which serves also as the one electrode terminal (for example, a cathode terminal), and an open mouth portion of the battery case 1 is closed tight by an external terminal plate 7 of the other electrode terminal (for example, an anode terminal) with an insulating sealing body 5 in-between. An outer circumferential surface of the battery case 1 is coated by an insulating external label 8 and the open mouth portion of the battery case 1 is closed tight with the external terminal plate by caulking inward an open end portion of the battery case 1 in an arc shape.
