- 正極板及び負極板をセパレータを介して交互に積層して積層体を形成し、該積層体を電解質と共に袋状の外装材内部に収納した扁平型電池において、
正極板と負極板のうち少なくとも一方の極板を二つ折りにしたセパレータに挟み、セパレータに挟まれた一方の極板と他方の極板とを交互に複数積層して前記積層体を構成し、
前記二つ折りにしたセパレータの折り目に相当する辺を除く残りの三辺のうちの何れかの辺における前記一方の極板に対する前記セパレータの余裕を他の二辺より小さくするとともに、前記セパレータの折り目に相当する辺以外の三辺は、前記極板の端部からはみ出すセパレータの上下の余裕部同士が接着されることなく、
前記袋状の外装材は、金属層の少なくとも一方面に樹脂層を備えた1枚のラミネートシートを、前記樹脂層を内側に2つ折りにして、前記セパレータの折り目に相当する辺の外側に、前記ラミネートシートの折り目に相当する辺を配置して、前記ラミネートシートの折り目に相当する辺を除く三辺の前記樹脂層を溶着して袋状に形成されていることを特徴とする扁平型電池。
