Abstract
A coated titanium material includes a titanium material and a coating film formed on a surface of the titanium material. A Ti-based oxide is included in an interface between the titanium material and the coating film. The Ti-based oxide is one or both rutile type TiOand TiO. In a case where a cut surface of the coating film is formed by using a SAICAS method under conditions that a horizontal speed is 2 μm/s and a vertical speed is 0.1 μm/s, on the cut surface, an area percentage of the Ti-based oxide is 30.0% or more in a region having a distance of 15 μm from a reference line specified on the basis of a boundary line, which is an intersection line between the cut surface and the interface, to a coating film side.
