PURPOSE: An electrode for a solar battery and a manufacturing method thereof are provided to have high permeability and low specific resistance by enhancing light absorption degree and to reduce manufacturing costs. CONSTITUTION: A thin film layer perpendicularly arrays a nanorod. The length of the nanorod is 0.5Mm to 2.0Mmfm. The diameter of the nanorod is 50nm to 200nm. The aspect ratio of the nanorod is 5.0 to 25.0. Amount of indium which is doped in the nanorod is 0.1 wt% to 0.5 wt%. The surface of a glass substrate is sputtered. A ZnO:In nanorod is formed on the glass substrate which is sputtered. An end portion of the A ZnO:In nanorod is etched.
