PURPOSE:To increase the toughness of a battery by making a terminal plate with a stainless steel plate having a specified hardness. CONSTITUTION:A flat type battery consists of a positive mix sheet 2, a separa tor 3, a frame-shaped insulator 4, a negative sheet 1, a negative terminal plate 5, and a positive terminal plate 6. The negative terminal plate 5 and/or the positive terminal plate 6 are/is made of stainless steel plate having a Vickers hardness of 250-270. Thereby, the toughness of the battery is increased and the flat battery withstanding screatch and breakage and showing good appear ance can be obtained. |
