Claims

[Scope of utility model registration request]

An electrode layer in which negative electrodes and positive electrodes are alternately laminated with separators interposed therebetween, a positive electrode can with an open top for storing the electrode layer, a flange-fitted negative electrode can that fits into the opening on the top surface of the positive electrode can, a positive electrode can, and a negative electrode can. and an insulating backing interposed between the two electrodes to insulate the space between the two electrodes and on which the collar of the negative electrode can is layered, and furthermore, the negative electrode surface electrode is brought into direct contact with the negative electrode can body to collect current from the negative electrode terminals from the second electrode onward. A button-type battery characterized by having its body connected to the flange of a negative electrode can.
