A cylindrical battery including 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 upper insulating plate disposed on the electrode body; a positive electrode current collector plate disposed on the upper insulating plate; a sealing body; and an outer can. A first positive electrode lead extends between the upper insulating plate and the current collector plate after passing through a through-hole of the upper insulating plate and is bent onto the current collector plate at an outer circumference portion thereof, and a second positive electrode lead extends along the outside of an outer circumference portion of the upper insulating plate and is bent onto the current collector plate at the outer circumference portion thereof. Those positive electrode leads are all connected to the current collector plate.
