A negative electrode including the negative electrode active material is produced. A non-aqueous electrolyte secondary battery including the negative electrode, a positive electrode, and an electrolyte solution is produced. The first graphite particle has a first number-based particle size distribution. The second graphite particle has a second number-based particle size distribution. A relationship of “D50/D50≤0.50” is satisfied. D50 is a D50 in the first number-based particle size distribution. D50 is a D50 in the second number-based particle size distribution. A relationship of “R≤R” is satisfied. Ris an arithmetic mean of circularity of the first graphite particle. Ris an arithmetic mean of circularity of the second graphite particle.",
