Titanium plate

A titanium plate, comprising:

• Fe:
• from 0.020 to 1.000 mass %;
• O:
• from 0.020 to 0.400 mass %;
• titanium;
• and
• inevitable impurities,
• and including a grain microstructure of α phase that has a HCP structure,
• wherein:
• a total area of α phase grains included in a first angle range (X1) where a first angle (θ) between a no al direction of the (0001) plane and a ND direction that is a normal direction of a rolling plane in an (0001) pole figure of an α phase grain is from 0° to 50° is 0.40 or more in terms of a ratio (P) relative to the total area of entire α phase grains;
• an area ratio (Q) expressed by (A)/(B) is from 0.20 to 5.00 with (A) being a total area of α phase grains included in a range where a second angle (φ) between a plane including the normal direction and the ND direction and a plane including the ND direction and a RD direction that is the rolling direction is from 0° to 45° in the first angle range (X1) and with (B) being a total area of α phase grains included in a range where the second angle (φ) is over 45° and 90° or less;
• the total area of α phase grains included in a second angle range (X2) where the first angle (θ) is from 80° to 90° is 0.15 or more in terms of a ratio (R) relative to the total area of entire α phase grains;
• an area ratio (S) expressed by (C)/(D) is from 0.20 to 5.00 with (C) being a total area of α phase grains included in a range where the second angle (φ) is from 0° to 45° in the second angle range (X2) and with (D) being a total area of α phase grains included in a range where the second angle (φ) is over 45° and 90° or less;
• and
• an average value of an equivalent circle diameter in the α phase grains is from 5 to 100 μm, and a maximum value of the equivalent circle diameter is 200 μm or less.
