Summary:PROBLEM TO BE SOLVED: To provide a solid lithium secondary battery with excellent charge discharge cycle characteristic. SOLUTION: This manufacturing method of a composite positive electrode for a lithium secondary battery comprises (1) a first process for forming an electrode layer composed of a mixture containing a 3V class Mn oxide, a conductive assistant, a binder, and an organic solvent on a current collector, (2) a second process for obtaining a plate by removing the organic solvent by drying the electrode layer, (3) a third process for press-forming the plate, and (4) a fourth process for impregnating a lithium ion conductive high polymer electrolyte into the electrode layer.
