(57) [Problem] To provide a secondary battery excellent in battery capacity, cycle characteristics, and charge / discharge efficiency. SOLUTION: This is a negative electrode for a secondary battery in which a current collector and a layer containing a carbonaceous material are laminated, and the packing density d of the layer containing the carbonaceous material is 0.9 ≦ d ≦ 1. 9 g / cm 3 and the X-ray intensity ratio I 002 / I 110 of the negative electrode is I A negative electrode for a secondary battery characterized by satisfying 002 / I 110 ≦ 2000 is used. |
