Claims

[Scope of utility model registration request]

A battery having a spiral electrode body formed by winding band-shaped positive and negative electrode plates through a separator, and the positive or negative electrode plate itself or the core of the positive or negative electrode plate forming the outermost end of the spiral electrode body. A cylindrical battery in which an exposed portion of the material is bent in a direction opposite to the spiral direction, and the bent portion in the opposite direction is electrically abutted within a container housing a spiral electrode body.
