PURPOSE: To provide a method for manufacturing an Al-Mg-Si alloy sheet for restraining ridging, wherein the method is capable of improving ridging resistance by applying a yield strength or more of forward tensile force to the alloy steel in a final rolling step during cold rolling of the alloy sheet, thereby actively suppressing development of Goss texture constituents developed during cold rolling. CONSTITUTION: In a method for manufacturing an Al-Mg-Si alloy sheet, the method for manufacturing the Al-Mg-Si alloy sheet for restraining ridging comprises the process of manufacturing the Al-Mg-Si alloy sheet such that the Al-Mg-Si alloy sheet has a Goss orientation fraction of 3% or less by applying a forward tensile force of 17 to 20 kgf to the alloy sheet in a final rolling step during cold rolling of the Al-Mg-Si alloy sheet such that tensile strain of the alloy sheet is maintained to 5 to 10%.
