To provide a lithium ion secondary battery in which wiring is easy and a breakage of an inner structure is hard to occur since it has a flexibility even if it has a large thin sheet area and which has excellent charge and discharge characteristics.
The lithium ion secondary battery is provided with a sheet shaped cathode 1 made from a power storing rubber elastic material on which an anode 2 is arranged in a part with a separator in-between, and at least a part of a surface of the partially arranged anode 2 is arranged to be exposed toward the same direction with the surface of the sheet shaped cathode 1, and on the surface of the cathode 1, there is arranged a cathode terminal 4 made conductive with the cathode, and on the surface of the anode 2, there is arranged an anode terminal 5 made conductive with the anode. An ion barrier layer 6 is made an anisotropic conductive film and an integrated power source with plenty of cells arranged plane can be obtained. Furthermore, in the above structure, the cathode and the anode can be reversed.
