GASKET, BATTERY USING THE GASKET, AND MANUFACTURING METHOD FOR THE BATTERY

To provide a gasket that is less susceptible to deterioration during assembly and less prone to reduction in insulation properties, a battery using the gasket, and a manufacturing method for the battery.SOLUTION: A gasket is a flexible member that is sandwiched between a flat plate member having a hole and a terminal member having a flange installed at the position of the hole. The gasket is plate-shaped and has an overall shape with a hole portion 10 formed at a position encircled by its outer circumference. At least a portion outside a middle portion 11, which is smaller than the outer circumference and larger than the hole portion 10, is an inclined surface portion 12, which is more inclined toward the outer side and away from the flat plate member side.SELECTED DRAWING: Figure 2 【課題】組み付け時における劣化が起こりにくく絶縁性が低下しにくいガスケット、そのガスケットを用いた電池、およびその電池の製造方法を提供すること。【解決手段】本開示技術に係るガスケットは、孔を有する平板部材とその孔の箇所に設置される鍔部を有する端子部材との間に挟み込まれる柔軟部材であって、板状であるとともにその外周に包囲されている位置に孔部１０が形成されている全体形状であり、少なくとも、外周より小さく孔部１０より大きい中間部１１より外側の部分が、外側寄りほど平板部材側から遠ざかる向きに傾斜している傾斜面部１２であるものである。【選択図】図２
