PROBLEM TO BE SOLVED: To provide a secondary battery which enables the enhancement of a performance.SOLUTION: A secondary battery comprises: a positive electrode; a negative electrode; and an electrolytic layer disposed therebetween. The electrolytic layer includes: a positive electrode-side electrolytic layer disposed on the side of the positive electrode; and a negative electrode-side electrolytic layer disposed between the positive electrode-side electrolytic layer and the negative electrode. The positive electrode-side electrolytic layer includes: a binder having a fluorine-based copolymer and including tetrafluoro ethylene; and an electrolyte. The negative electrode-side electrolytic layer includes a butadiene rubber-based binder and an electrolyte. |
