Provided is a 7000-series aluminum alloy sheet that is for an automobile part and that is provided with both strength and stress corrosion cracking resistance. The cold-rolling rate and solution treatment conditions are controlled of an Al—Zn—Mg alloy sheet having a specific composition and produced by means of a conventional method. Also, the structure has a low average crystal size, an average fraction of low-angle grain boundaries at an inclination angle of 5-15° of at least 15%, and an average fraction of high-angle grain boundaries at an inclination angle exceeding 15° of 15-50%. Alternatively, there is a specific aggregate structure having a low average crystal size, and a total area ratio of the specific orientation of the Brass orientation, S orientation, Cu orientation, and the like of at least a set amount.
