Abstract: An Al—Mg—Si type alloy sheet contains 0.2 to 1.5 wt % of Mg and 0.2 to 1.5 wt % of Si. The sheet has textures in which orientation distribution density of Goss orientation is 3 or lower, orientation distribution density of PP orientation is 3 or lower and orientation distribution density of Brass orientation is 3 or lower. The sheet may contain 0.01 to 1.5 wt % in total weight of one or more elements selected from the group consisting of Mn, Cr, Fe, Zr, V and Ti. The sheet may further contain 0.01 to 1.5 wt % in total weight of one or more elements selected from the group consisting of Cu, Ag, Zn and Sn. Thus, ridging marks is restrained in the aluminum alloy sheet.
