NOVELTY - A positive electrode (3) comprises positive-electrode active material (a), sulfide type solid electrolyte (b) and binder (c). The positive-electrode active material is lithium-cobalt oxide, lithium-manganese oxide, lithium-nickel-cobalt oxide and/or lithium-nickel-cobalt-aluminum oxide. The sulfide type solid electrolyte is sulfide type glass or sulfide type glass ceramics containing lithium, phosphorus and sulfur. The average particle diameter of solid electrolyte is 0.1-50 mu m. The binder is a resin having ethylene-oxide structure, or thermoplastic elastomer.    USE - Positive electrode is used for all-solid-state lithium secondary battery (claimed) used as power supply for motor vehicles, mobile telephone and personal computer.    ADVANTAGE - The all-solid-state lithium secondary battery comprising positive electrode has excellent electrochemical capacitance, charging-and-discharging efficiency, and high output.    DETAILED DESCRIPTION - A positive electrode comprises positive-electrode active material (a), sulfide type solid electrolyte (b) and binder (c). The positive-electrode active material is lithium-cobalt oxide (LiCoO2), lithium-manganese oxide (LiMn2O4), lithium-nickel-cobalt oxide (LiNixCoyO2, where x+y is 1) and/or lithium-nickel-cobalt-aluminum oxide (LiNixCoyAlzO2, where x+y+z is 1). The sulfide type solid electrolyte is sulfide type glass or sulfide type glass ceramics containing lithium, phosphorus and sulfur. The average particle diameter of solid electrolyte is 0.1-50 mu m. The binder is a resin having ethylene-oxide structure, or thermoplastic elastomer. The mass ratio of components (a and b) is 3:7-9:1. When component (c) is thermoplastic elastomer, the mass ratio of components (a+b) with respect to component (c) is 99.9:0.1-99.5:0.5. When component (c) is resin having ethylene-oxide structure, the mass ratio of components (a+b) with respect to component (c) is 99:1-95:5.
