Abstract (en)
A titanium sintered body contains an ±-phase and a ²-phase as crystal structures, wherein the average grain size of the ±-phase in a cross section is 3 µm or more and 30 µm or less, and an area ratio occupied by the ±-phase in a cross section is 70% or more and 99.8% or less. In the titanium sintered body, it is preferred that the average aspect ratio of the ±-phase in a cross section is 1 or more and 3 or less. It is also preferred that the titanium sintered body contains titanium as a main component, and also contains an ±-phase stabilizing element and a ²-phase stabilizing element.
