Abstract
A laminated lithium primary battery is provided which can prevent battery life deterioration caused by moisture penetration from outside and in which safety and increase of battery capacity both can be realized. A lithium primary battery 1, including: a sheet-like negative electrode 30 made of lithium; a sheet-like positive electrode 20; a sheet-like separator 40 made of cellulose; non-aqueous organic electrolytic solution; a jacket 11 made of laminate films (11a and 11b), an inside of the jacket is sealed by heat-sealing periphery of the laminate film stacked in an up-and-down direction; and an electrode assembly 10 in which the positive electrode 20 and the negative electrode 30 are stacked in the up-and-down direction having the separator 40 therebetween, the sealed jacket 11 accommodating the electrode assembly with the non-aqueous organic electrolytic solution.
