摘要
A negative electrode includes current collector (11) in which concave portion (12) and convex portion (13) are formed at least one surface thereof, and columnar body (15) which is formed by laminating n (n‰¥2) stages of columnar body portions (151 to 158) which are formed on convex portion (13) of current collector (11), and includes columnar body portions (151 to 158) in which variation direction of content ratios of elements of odd-numbered stages of columnar body portions and that of even-numbered stages of columnar body portions are different from each other, and plural protruding bodies (16) are provided on the surfaces of columnar body portions (151 to 158) at the side in which intersection angles between central lines of obliquely erected directions of columnar body portions (151 to 158) and a central line of a thickness direction of current collector (11), and space (17) is provided in columnar body (15) by protruding bodies (16) of the laminated columnar body portions (151 to 158).
