PROBLEM TO BE SOLVED: To provide a titanium alloy sheet having high strength and excellent deep drawability, and to provide a method for producing a titanium alloy sheet, with which the titanium alloy sheet having high strength and excellent deep drawability can be surely obtained.;SOLUTION: The titanium alloy sheet comprises, by mass, ≥0.1% O and a β stabilization element by ≤0.5% (excluding 0%), and in which the average value of an inclination angle formed between the normal of the (0001) face in the α phase and the normal of the rolling face is≤45°, and the area ratio of the α phase in which the inclination angle θ is ≥50° occupying in the whole α phase is ≤10%. Further, as the β stabilization element, Fe is preferably comprised.;COPYRIGHT: (C)2010,JPO&INPIT
