PROBLEM TO BE SOLVED: To provide an Al or Al alloy sheet for press-forming, excellent in press-formability. SOLUTION: The Al alloy sheet for press-forming is the Al alloy sheet 1 in which the orientation density in the Cube orientation, which is the main orientation of a texture, is≥20 and the orientation densities in individual orientations other than the Cube orientation are≥10. When a part 5 with the largest strain in a plane strain deformation region 4 exists in a planar region 3 of a press-formed product 2 made of the Al alloy sheet, the interior angleαbetween a normal direction 7 and a rolling direction 8 of the Al alloy sheet 1 can be adjusted to 45±10°so as to control the texture of the Al alloy sheet and the anisotropy of the plane strain deformation and improve the press-formability, wherein the normal direction 7 corresponds to a line 6 normal to the part 5 in a top view of the press-formed product 2.
