PROBLEM TO BE SOLVED: To provide a battery excellent in strength and corrosion resistance, capable of being soldered and spot-welded easily, and provided with inexpensive positive and negative electrode lead terminals. SOLUTION: This battery is provided with a film 13 for storing a power generation element 1 in such condition that tips of a positive electrode lead terminal 11 and a negative electrode lead terminal 12 are protruded outside. The lead terminal 11 comprises a band-like metal plate including a nickel region 16 formed at least in a connecting margin of its one face or both faces not to contact with the film 13, and an aluminum region formed in a portion located within the film 13. The lead terminal 12 comprises a band-like metal plate including the nickel region 16 formed at least in a connecting margin of its one face or both faces not to contact with the film 13, and a copper region formed in a portion located within the film 13. |
