- 正極材を含む発電要素を収容する電池缶が、底面壁の外周から外周筒壁を上向きに曲げた正極缶と、上面壁の外周から外周側壁を下向きに曲げた負極缶とを含み、前記負極缶の前記外周側壁と、該外周側壁に装着された絶縁性のガスケットとを前記正極缶内に嵌め込んだ状態で、前記正極缶の前記外周筒壁の開口上端部分を内向きにかしめ加工することにより、前記ガスケットの下端部が、前記正極缶の前記底面壁と前記負極缶の前記外周側壁との間に挟み込まれているコイン形電池において、
前記正極材に装着される正極リングを有し、
前記正極リングは、前記正極材の外周側面を囲む筒部と、該筒部の下端から外方へ張り出したフランジ部とを備えており、
前記フランジ部の外径寸法が、前記ガスケットの下端部の内径寸法に等しいかあるいは僅かに小さく設定されており、
前記フランジ部の外周縁が前記ガスケットの下端部に当接することで、前記正極リングの位置ずれを防いでいるコイン形電池。 - 前記ガスケットが、弾性を有する請求項1記載のコイン形電池。
- 前記正極リングが導電性を有し、
前記フランジ部の下面が、前記正極缶の前記底面壁に接している請求項1又は2記載のコイン形電池。
