According to the invention, a non-aqueous electrolyte secondary battery including a positive electrode, a negative electrode, and a non-aqueous electrolyte is provided. The negative electrode contains a negative electrode active material, a conductive material, and a binder. When an average particle size of the conductive material is referred to as De, and an average particle size of the binder is referred to as Db, Db≤De is satisfied. In other words, the average particle size Db of the binder is equal to or smaller than the average particle size De of the conductive material.
