A battery including: a battery can including a cylinder portion including an opening edge portion at one end portion of the cylinder portion and a bottom portion that closes the other end portion of the cylinder portion; an electrode body; a sealing member that seals an opening of the opening edge portion. The sealing member includes: a sealing plate; a cap connected to the sealing plate and electrically insulated from the sealing plate; and a sealing portion sealing a space between the cylinder portion and the cap. The cap includes: a ring-shaped top plate portion opposing the opening edge portion in an axial direction of the cylinder portion; and a side wall portion covering an outer circumferential surface of the cylinder portion. The sealing portion may be a gasket provided between the cap and the cylinder portion in a compressed state. The cap is electrically connected to the cylinder portion.
