Abstract: Corrosion inhibitors for hypochlorous acid aqueous solutions are provided and impart corrosion inhibiting effects of suppressing the generation of rust in contacted metal surfaces to hypochlorous acid aqueous solutions. Effective components of the corrosion inhibitors comprise only: an A component composed of (A1) a metal salt of formic acid and/or (A2) a metal salt of saturated carboxylic acid, wherein the number n of carbon atoms contained in the molecule is at least 2, the valence v of the acid is 1 or 2, and the value n/v obtained by dividing the number n of carbon atoms by the valence v of the carboxylic acid is 2-6; and a B component composed of a nonionic surfactant, wherein the mass ratio B/A of the B component to the A component in the effective component is 0.005-10.0.
