Abstract

The aluminum alloy material of the present disclosure has a specific alloy composition and has a fibriform metallographic structure where crystal grains extend so as to be aligned in one direction, wherein an average value of a size perpendicular to a longitudinal direction of the crystal grains is 400 nm or less in a cross section parallel to the one direction. The aluminum alloy material of the present disclosure has a main surface having a crystal orientation distribution which satisfies a peak intensity ratio R (I 200 /I 220 ) of a peak intensity I 200 of a diffraction peak due to a {100} plane to a peak intensity I 220 of a diffraction peak due to a {110} plane, of 0.20 or more, determined by an X-ray diffraction method.
