    摘要： A titanium plate according to an aspect of the present invention includes, as a chemical composition, in mass%, O: 0.02% to 0.15%, Fe: 0.02% to 0.20%, N: 0 to 0.08%, C: 0 to 0.100%, and H: 0 to 0.013%, and a remainder including Ti and impurities, in which when the crystal orientation of an α phase is represented by an Euler angle g = (ϕ1, Φ, ϕ2), the area fraction of the α phase having a crystal orientation in which the absolute value of an orientation difference with respect to (0°, 90°, 0°) is within 30° is defined as X1, the area fraction of the α phase having a crystal orientation in which the absolute value of an orientation difference with respect to (0°, 90°, 30°) is within 30° is defined as X2, and the area fraction of the α phase having a crystal orientation in which absolute values of orientation differences with respect to both (0°, 90°, 0°) and (0°, 90°, 30°) are within 30° is defined as X1&2, X1 + X2 - X1&2 is 0.075 or less.
