Zusammenfassung:This titanium alloy sheet contains predetermined chemical components, an area ratio of an α-phase is 80% or more, an area ratio of the α-phase having an equivalent circle diameter of 1 μm or more is more than 53%, and in a (0001) pole figure in a sheet thickness direction, an angle formed between the sheet thickness direction and a direction indicating a peak of intensity calculated by texture analysis in a case in which a series rank is 16 and the Gaussian half width is 5° for an inverse pole figure using a spherical harmonics method of an electron backscatter diffraction method is 65° or less, and the average sheet thickness is 2.5 mm or less.
