PROBLEM TO BE SOLVED: To provide a new beta titanium alloy having excellent press formability, which has low proof stress after solution heat treatment, high ductility and excellent cold workability and hardly causes rough surface even when subjected to complicated forming. SOLUTION: The titanium alloy has a composition consisting of (by mass, the same applies to the following) 12 to 20% V, 0.5 to 3.5% Fe, 4 to 15% Sn,≤0.15% (not including 0%) O and the balance Ti with inevitable impurities.
