PROBLEM TO BE SOLVED: To provide an exposed base metal covering method capable of easily covering an exposed portion of a covered base metal, and depositing a film of excellent adhesibility to a cover film and corrosion resistance. SOLUTION: In this exposed base metal covering method, the exposed portion of a covered metal is covered with titanium-based metal surface treatment agent containing (A) titanium-containing aqueous solution obtained by mixing hydrogen peroxide with at least one kind of titanium compound selected from the group consisting of hydrolytic titanium compound, low-condensate of hydrolytic titanium compound, and low-condensate of hydrated titanium and hydrolytic titanium, and (B) at least one kind of compound selected from a group consisting of organic acids, organic acid salts, metal salts of hydrofluoric acid, metal salts of hydrofluoric acid salt, ammonium, and organic basic compound.
