A method for manufacturing an electrode having a laminated body including an insulating layer laminated on an electrode active material layer, said method comprising: a step of laminating an insulating layer on an electrode active material layer formed on a base, such that a thickness value of the insulating layer is at least twice a surface roughness Rz value of the electrode active material layer, the surface roughness Rz value being a ten point average roughness as measured in accordance with JIS B0601 1994.
