Abstract
A cylindrical battery according to one aspect of the present invention includes an electrode body in which a negative electrode plate and a positive electrode plate to which a plurality of positive electrode leads is connected are wound with a separator interposed therebetween; an electrolyte liquid; a cylindrical outer can having a bottom portion which receives the electrode body and the electrolyte liquid; and a sealing body sealing an open portion of the outer can. The positive electrode leads extend along an outer circumference portion of a collector member disposed on the electrode body and are connected to a surface of the collector member at an outer side of the battery. The collector member includes a collector plate to which the positive electrode leads are connected and a first insulating plate fitted to a surface of the collector plate at an inner side of the battery.
