Abstract
A titanium substrate of the present invention includes a substrate main body formed of titanium or a titanium alloy, in which a Magneli phase titanium oxide film formed of a Magneli phase titanium oxide represented by a chemical formula TinO2n-1 (4≤n≤10) is formed on a surface of the substrate main body and a BET value of the substrate main body on which the Magneli phase titanium oxide film is formed is 0.1 m2/g or less.
