PROBLEM TO BE SOLVED: To provide a separator for a nonaqueous electrolyte secondary battery capable of improving battery life and being excellent in increasing capacity, and to provide a nonaqueous electrolyte secondary battery including the same and being excellent in safety and cycle characteristics.SOLUTION: Liquid containing an organic semiconductor, fine particles, and a medium is applied to a microporous film, and then, the medium is removed. Alternatively, liquid containing an organic semiconductor, fine particles, and a medium is applied onto a supporting body, and then, the medium is removed, and a porous film containing the organic semiconductor and the fine particles is peeled off from the supporting body. Thereby, a separator for a nonaqueous electrolyte secondary battery in which the organic semiconductor and the microporous film are laminated is manufactured, and a nonaqueous electrolyte secondary battery using the same is obtained. |
