PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery having both excellent input/output characteristics and high durability (good cycle characteristics).SOLUTION: The present invention provides a nonaqueous electrolyte secondary battery including a positive electrode, a negative electrode and a nonaqueous electrolyte. The negative electrode includes a negative electrode active material 22, an electro-conductive material 24, and a binder 26. When the average particle size of the electro-conductive member 24 is denoted as De and the average particle size of the binder 26 is denoted as Db, Db≤De is satisfied. That is, the average particle size Db of the binder 26 is equal to or less than the average particle size Db of the electro-conductive material 24.SELECTED DRAWING: Figure 1 |
