Abstract
A thin battery includes a sheet-like electrode assembly; a non-aqueous electrolyte with which the electrode assembly is impregnated; and a housing in a sealed manner. The electrode assembly includes a pair of first electrodes located at an outermost side of the electrode assembly, a second electrode interposed between the pair of first electrodes, and a separator disposed between each first electrode and the second electrode. The first electrode includes a first current collector sheet and a first active material layer attached to one surface of the first current collector sheet. The second electrode includes a second current collector sheet and second active material layers attached to both surfaces of the second current collector sheet. A content x of the non-aqueous electrolyte per unit area of the first active material layer is larger than a content y of the non-aqueous electrolyte per unit area of the second active material layer.
