Claims

[Scope of utility model registration request]

A vertical notch in the internal peripheral wall into which the spiral electrode plate group is inserted, through which the current collector of either the positive or negative electrode plate located at the outermost periphery of the spiral electrode plate group extends to the outside. The cylindrical battery is provided with a cutout portion, and the current collector extending outward from the cutout portion is sandwiched between an outer wall of the inner can and an inner wall of the outer can that also serves as a terminal body of one pole.
