PROBLEM TO BE SOLVED: To provide a titanium alloy material for a spectacle frame having a composition achieving a low Young's modulus, high strength, high biocompatibility, easy brazing and satisfactory workability. SOLUTION: The titanium alloy material for a spectacle frame includes a metal crystal structure where the main phase is composed of aβphase, and the titanium alloy material for a spectacle frame has a composition comprising 19.0 to 35.0 at% tantalum, 1.0 to 9.0 at% aluminum, and the balance titanium with inevitable impurities.
