    • The present invention maintains a power generating element in a flat shape as far as possible to thereby improve workability in a manufacturing process. In a battery including a power generating element formed into a flat shape and housed in a container, the power generating element formed by winding a foil-shaped positive electrode plate 24a and a foil-shaped negative electrode plate 24b, with separator 25 sandwiched therebetween, about a winding core 21 having flexibility, a thin-plate-shaped member TP having higher rigidity than the winding core is attached to at least one of opposite end portions in a direction of a winding axis of the winding core 21.
    • 本发明将发电元件尽可能地保持为扁平形状,从而提高了制造工序的作业性。 在包括形成为平坦形状且容纳在容器中的发电元件的电池中,通过卷绕箔片状的正极板24a和箔状负极板24b而形成的发电元件,隔着隔板25夹在其间, 关于具有柔性的卷绕芯21,具有比卷芯更高刚性的薄板状构件TP沿着卷绕芯21的卷绕轴的方向附接到相对端部中的至少一个。
