Abstract
A titanium plate according to the present invention contains a predetermined amount of Fe and O with the remainder consisting of titanium and inevitable impurities, and has a grain microstructure of the α-phase having a HCP structure. In the titanium plate, the total area in which α-phase grains specified by a first angle (θ) are included is a predetermined value of a ratio (P) or (R) and the total area in which α-phase grains specified by a second angle (φ) are included is a predetermined value of an area ratio (Q) or (S) in a (0001) pole figure of α-phase grains, and the average value and the maximum value of an equivalent circle diameter in the α-phase grains are respectively predetermined values.
