A method for manufacturing an electrode for a secondary battery, the method comprising: supplying a collector having a long sheet shape and being continuously supplied; applying an electrode active material to a surface of the collector to manufacture an unfinished electrode; rolling, by using a rolling roller, a surface of the unfinished electrode and adjusting a thickness of the electrode active material to manufacture a finished electrode; and measuring a surface roughness of the rolling roller, measuring a surface roughness of the electrode active material applied to the finished electrode, determining the finished electrode as a normal product when the surface roughness value of the rolling roller is within a range of an inputted surface roughness value of the rolling roller and the surface roughness value of the finished electrode is within a range of the inputted surface roughness value of the electrode, determining the finished electrode as a product to be re-inspected when the surface roughness value of the rolling roller is within the range of an inputted surface roughness value of the rolling roller and the surface roughness value of the finished electrode is out of the range of the inputted surface roughness value of the electrode, or when the surface roughness value of the rolling roller is out of a range of an inputted surface roughness value of the rolling roller and the surface roughness value of the finished electrode is within the range of the inputted surface roughness value of the electrode, and determining the finished electrode as an abnormal product when the surface roughness value of the rolling roller is out of the range of the inputted surface roughness value of the rolling roller and the surface roughness value of the finished electrode is out of the range of the inputted surface roughness value of the electrode. supplying a collector having a long sheet shape and being continuously supplied; applying an electrode active material to a surface of the collector to manufacture an unfinished electrode; rolling, by using a rolling roller, a surface of the unfinished electrode and adjusting a thickness of the electrode active material to manufacture a finished electrode; and measuring a surface roughness of the rolling roller, measuring a surface roughness of the electrode active material applied to the finished electrode, determining the finished electrode as a normal product when the surface roughness value of the rolling roller is within a range of an inputted surface roughness value of the rolling roller and the surface roughness value of the finished electrode is within a range of the inputted surface roughness value of the electrode, determining the finished electrode as a product to be re-inspected when the surface roughness value of the rolling roller is within the range of an inputted surface roughness value of the rolling roller and the surface roughness value of the finished electrode is out of the range of the inputted surface roughness value of the electrode, or when the surface roughness value of the rolling roller is out of a range of an inputted surface roughness value of the rolling roller and the surface roughness value of the finished electrode is within the range of the inputted surface roughness value of the electrode, and determining the finished electrode as an abnormal product when the surface roughness value of the rolling roller is out of the range of the inputted surface roughness value of the rolling roller and the surface roughness value of the finished electrode is out of the range of the inputted surface roughness value of the electrode.
