Abstract
A current collector for a lithium ion secondary battery, on which an electrode mixture layer is formed, satisfies A≥0.10 μm and 6≤(B/A)≤15 when assuming that a three-dimensional center plane average roughness SRa of a surface of at least one side of the current collector on which the electrode mixture layer is formed is A and a ratio of an actual surface area of the surface of at least one side of the current collector to a geometric area of the surface of at least one side of the current collector, which is (actual surface area)/(geometric area), is B.
