A high-strength titanium plate having excellent ductility and a method for producing the same can be provided. SOLUTION: In mass%, Fe: 0.8 to 1.5%, O: 0.25 to 0.40%, the remainder has a chemical composition consisting of Ti and impurities, recrystallized, etc. It has a two-phase structure consisting of an axial α phase and a β phase, the area ratio of the equiaxed α phase is 70 to 85%, the average crystal grain size of the β phase is 3 μm or less, and the number of β phases is the rolling width direction In the cross section, 0.02 or more exist on average within an area of 1 μm 2 .
