A secondary battery includes an electrode wound body, a first electrode current collector plate, a second electrode current collector plate, an electrolytic solution, and a battery can. The first electrode current collector plate faces a first end face of the electrode wound body. The second electrode current collector plate faces a second end face of the electrode wound body. In the electrode wound body, an outermost wind part of a second electrode is located on an outer side relative to an outermost wind part of a first electrode. A sidewall part of the battery can includes a thin part, and a thick part that protrudes toward an inner side of the battery can along a radial direction. The thick part is located to overlap, in the radial direction, an end part, of the first electrode covered part, located on a side of the first end face in the first direction.
