A secondary battery including an electrode wound body having a structure in which a positive electrode and a negative electrode are stacked and wound with a separator interposed therebetween, a positive electrode current collector plate; a negative electrode current collector plate, and an exterior can that accommodates the electrode wound body, the positive electrode current collector plate, and the negative electrode current collector plate. The positive electrode has a first covered portion covered with a positive electrode active material layer and a positive electrode active material non-covered portion on a band-shaped positive electrode foil, and the negative electrode has a second covered portion covered with a negative electrode active material layer and a negative electrode active material non-covered portion on a band-shaped negative electrode foil.
