    • PROBLEM TO BE SOLVED: To provide a positive electrode in which a positive electrode active material layer of a thick film is formed on a positive electrode current collector, and to provide a method of manufacturing the same. SOLUTION: When manufacturing the positive electrode that becomes the positive electrode layer 1 of a non-aqueous electrolyte battery 100, a substrate that becomes the positive electrode current collector 11 of the positive electrode layer 1, and the positive electrode active material that becomes a constituting material of the positive electrode active material layer 12 is prepared. A relationship between a thermal expansion coefficient Tp(10 -6 /°C) of the positive electrode active material and the thermal expansion coefficient Tc (10 -6 /°C) of the positive electrode current collector is set to be Tp+2.5≥Tc≥Tp-2.5. Then, on the prepared positive electrode current collector 11, the positive electrode active material layer 12 with a thickness of ≥5 μm is formed by a vapor phase method, and annealed at 550-650°C. By a series of the processes, the positive electrode having the crystallized positive electrode active material layer 12 with the thickness of ≥5 μm can be manufactured. COPYRIGHT: (C)2011,JPO&INPIT
