Abstract
A battery can of the present invention ensures a stable and favorable contact with an electrode and thus makes it possible to obtain a highly reliable battery excellent in high rate discharge characteristics. The battery can having an opening, including a cylindrical side portion and a bottom portion, of the present invention is formed from a steel plate. The steel plate has an Ni—Fe alloy layer on the inner face side of the battery can. The Ni—Fe alloy layer has an oxide layer containing iron and having a thickness of 10 to 50 nm on the inner face side of the battery can.
