Titanium material and coated titanium material

A coated titanium material comprising:

• a titanium material;
• and
• a coating film formed on a surface of the titanium material,
• wherein 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 TiO2 and Ti2O3,
• in a case where a cut surface of the coating film is formed under conditions that a horizontal cutting speed is 2 μm/s and a vertical cutting 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, which is perpendicular to a lamination direction of the coating film, and which is tangent to a point closest to the coating film in a boundary line, which is an intersection line between the cut surface and the interface on the cut surface, to a coating film side, and
• wherein the coating film is a uniform electrodeposition coating film including a modified epoxy resin.
