A lithium-ion secondary battery 10 consisting of a laminar member 40 including a positive electrode collector layer 12, a positive electrode layer 16 consisting of a vapor-deposited polymer film 26 containing a positive electrode active substance 24, and positive-electrode-side vapor-deposited polymer films 36, 37, which are integrally laminated on each other, and a laminar member 42 including a negative electrode collector layer 14, a negative electrode layer 18 consisting of a vapor-deposited polymer film 30 containing a negative electrode active substance 28, and negative-electrode-side vapor-deposited polymer films 38, 39, which are integrally laminated on each other. The laminar members 40, 42 are superposed on each other such that the vapor-deposited polymer films 36, 37 are in contact with the vapor-deposited polymer films 38, 39. The vapor-deposited polymer films 36, 37, 38, 39 constitute a solid electrolyte layer 20. |
