Zusammenfassung:	Provided is a nonaqueous electrolyte secondary battery laminated separator that makes it possible to reduce an increase in alternating-current resistance after compression. A nonaqueous electrolyte secondary battery in accordance with an embodiment includes: a nonaqueous electrolyte secondary battery functional layer; and a polyolefin base material, the nonaqueous electrolyte secondary battery functional layer and the polyolefin base material being formed on top of each other, after the nonaqueous electrolyte secondary battery laminated separator is subjected to pressure application at 20 MPa, the nonaqueous electrolyte secondary battery functional layer having a compressibility of not less than 15%, and the polyolefin base material having a compressibility of not more than 5%.
