摘要： An anode capable of improving cycle characteristics and a battery using it are provided. An anode active material layer containing Si is provided on an anode current collector. The anode current collector is roughened by providing a projection on a base material with a ten point height of roughness profile Rz1 of 2.0 μm or less. A value of a difference, Rz2−Rz1 obtained by subtracting the ten point height of roughness profile Rz1 of the base material from a ten point height of roughness profile Rz2 of the anode current collector is from 0.2 μm to 5.1 μm. Thereby, even when the anode active material is expanded and shrunk due to charge and discharge, breakage of the anode current collector, fall off of the anode active material layer and the like can be prevented.
