PROBLEM TO BE SOLVED: To provide a treatment liquid for forming an oxidation-resistant film on a surface-coated cermet member, which can easily form the oxidation-resistant film that can improve oxidation resistance while maintaining the superior performance of a titanium-based sintered body. SOLUTION: The treatment liquid has a composition including a metal salt which reacts with a titanium compound to produce an ilmenite-type composite oxide. It is preferable that the metal salt is a compound of a transition metal having a divalent ion in an iron group. The oxidation-resistant film 12 containing the ilmenite-type composite oxide can be formed by applying the treatment liquid to the cermet substrate 11 and heating the applied liquid.
