Summary:To provide a battery that is excellent in discharge capacity maintenance property and dendrite resistance, that is light in weight, and that has a good heat resistance.SOLUTION: Provided is a battery that includes a positive electrode, a negative electrode, a non-aqueous electrolyte, and an ion conduction polymer film. The concentration of at least one kind of metal ion in the non-aqueous electrolyte is higher than 3 mol/L. The air permeability of the ion conduction polymer film is equal to or more than 1,000 sec/100 cc, and the ionic conductivity thereof is equal to or more than 1.0×10-5 S/cm.SELECTED DRAWING: None 【課題】放電容量維持持性と耐デンドライト性に優れ、軽量かつ良好な耐熱性を有する電池を提供すること。【解決手段】正極、負極、非水電解質およびイオン伝導ポリマー膜を含む電池であって、上記非水電解質中の少なくとも１種類の金属イオン濃度が３ｍｏｌ／Ｌより高く、上記イオン伝導ポリマー膜が透気度１０００秒／１００ｃｃ以上かつイオン伝導度が１．０×１０－５Ｓ／ｃｍ以上である電池。【選択図】なし
