PROBLEM TO BE SOLVED: To provide a lithium battery which remains small in internal resistance until a discharge end stage, and which is superior in pulse characteristic at a low temperature.SOLUTION: A lithium battery 1 comprises: an electrode body 10; a nonaqueous organic electrolytic solution; and an outer packaging body 11 in which the electrode body and nonaqueous organic electrolytic solution sealed. In the electrode body, a sheet-like or tabular negative electrode 30 including metallic lithium or a lithium alloy as a negative electrode active material, and a positive electrode 20 including a positive electrode active material capable of occluding lithium ions are opposed to each other through a separator 40. The negative electrode is arranged by filling the negative electrode active material into a sheet-like or tabular metal porous body.SELECTED DRAWING: Figure 1 【課題】放電末期まで内部抵抗が小さく、低温時におけるパルス特性にも優れたリチウム電池を提供する。【解決手段】金属リチウムあるいはリチウム合金を負極活物質としたシート状あるいは平板状の負極３０と、リチウムイオンの吸蔵が可能な正極活物質を含む正極２０とがセパレーター４０を介して対向配置されてなる電極体１０が非水系有機電解液とともに外装体１１内に封入されてなるリチウム電池１であって、前記負極はシート状あるは平板状の金属多孔体に前記負極活物質が充填されてなることを特徴とするリチウム電池としている。【選択図】 図１
