- 開口部を有するケースと、
前記ケース内に収納される電極体と、
前記ケースの開口部を密閉する蓋部材と、
前記蓋部材の外面に設けられる外部端子と、
一端が前記電極体から延出する電極タブと電気的に接続され、他端が電池内部に設けられた電流遮断機構に電気的に接続される集電部材と、
電池内部において前記集電部材に電流遮断機構を介して電気的に接続される板状部と、前記板状部から突出して前記蓋部材を貫通して前記外部端子に電気的に接続される柱状部とを有する導通部材と、
前記導通部材の柱状部の外周に配置されて前記蓋部材の貫通孔との間を気密状態にシールするガスケットと、を備え、
前記電流遮断機構は、外周部が前記導通部材の板状部に接続され、内周部が前記集電部材の脆弱部に接続される薄板状の導電板を備え、前記導電板は電池内部の圧力上昇を受けて前記内周部が前記脆弱部の破断により前記集電部材から離間するように変位可能であり、
電池上面からの透視において前記導電板は前記ガスケットから離れた位置に配置されている、密閉型電池。 - 電池上面からの透視における前記導電板と前記ガスケットとの間の距離は3〜10mmの範囲内である、請求項1に記載の密閉型電池。
- 前記導通部材の板状部には、前記集電部材から離間変位した前記導電板の内周部を受け入れる収容凹部が前記板状部の厚み方向の内部に形成されている、請求項1または2に記載の密閉型電池。
