The present invention is a method of manufacturing an electrode for a secondary battery in which an electrode active material is applied to a current collector, and forms a surface roughness (R a ) having a size of 0.001 to 10 μm over the entire surface. A surface treatment of the current collector to have a morphology, and the surface treatment is performed by chemical or electrical etching by a wet method or reactive gas or ion etching by a dry method, Provided is a method for producing an electrode for a secondary battery characterized by improving the adhesive force with a current collector, and an electrode produced using the method. |
