A battery includes a can that includes a base material including iron and a nickel layer provided on a surface of the base material, an electrode element accommodated in the can, an insulating plate provided between the electrode element and a bottom of the can, and a metal-containing material provided between the insulating plate and the bottom of the can. An oxidation-reduction potential of the metal-containing material in a non-aqueous electrolytic solution is 1.5 V (vsLi/Li+) or higher an lower than 3.25 V (vsLi/Li+).
