NOVELTY - Nonaqueous electrolyte secondary battery has electrode component having structure in which positive electrode and negative electrode are laminated with separator. A porous filler layer is formed between the positive electrode and separator. The filler layer contains filler containing inorganic material and binder. The average thickness of the filler layer is greater than the average particle diameter of positive electrode active material contained in positive electrode which faces the filler layer.    USE - Nonaqueous electrolyte secondary battery e.g. assembled battery (claimed) used as power supply for personal computer, portable terminals, hybrid vehicle, electric vehicle and motor vehicle.    ADVANTAGE - The nonaqueous electrolyte secondary battery has excellent output characteristics, durability, and cycle characteristics, and suppressed leakage of current.    DETAILED DESCRIPTION - Nonaqueous electrolyte secondary battery has electrode component having structure in which positive electrode and negative electrode are laminated with separator. A porous filler layer is formed between the positive electrode and separator. The filler layer contains filler containing inorganic material and binder. The average thickness of the filler layer is greater than the average particle diameter of positive electrode active material contained in positive electrode which faces the filler layer. The pressure applied in the lamination direction to the electrode component is 0.1 MPa or more. An INDEPENDENT CLAIM is included for assembled battery.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view explaining relationship between average thickness of filler layer and average particle diameter of positive electrode active material.
