Disclosed are a surface-treated titanium material that is excellent in oxidation resistance and allows the excellent oxidation resistance to last for a long period of time and the surface treatment itself to be applied safely at a low cost; the production method thereof; and an exhaust system thereof. A surface-treated titanium material produced by forming an oxidation-resistant baked film 5 μm or more in thickness on a substrate comprising commercially pure titanium or titanium-base alloy, and said baked film is formed by filling the gaps among particles comprising Al alloy containing Si by 10 at % or less or commercially pure aluminum with chemical compounds comprising a metallic element M (M represents one or more of Ti, Zr, Cr, Si and Al) and C and/or O.
