Abstract: PROBLEM TO BE SOLVED: To provide a high molecular electrolyte for a lithium secondary battery, which makes penetration amount of electrolyte contained with dissolved lithium salt as well as mechanical strength higher by containing inorganic filler such as silica, and realize rapidly stability of interface resistance to the lithium electrode, and also to provide a method of high polymer electrolyte for lithium secondary buttery in which manufacturing process is simple as there removes use of plasticizer being extracted after molding the high polymer film. SOLUTION: The high molecular electrolyte for lithium secondary battery contains matrix formed from high polymer and inorganic filler, organic solvent electrolyte of lithium salt penetrated into the matrix.
