To provide corrosion-proof steel having excellent anti-fouling property and rust resistance, keeping the appearance for a long time, having excellent adhesiveness while peel of or damage to a coating film hardly occurs in a working process or the like, and a to provide a method for producing the same.

The corrosion-proof steel includes a base iron, a galvanized film as a first layer coating film provided on a surface of the base iron, and a zinc-containing corrosion-proof coating film as a second layer coating film formed on the first layer coating film and consisting of corrosion-preventive compositions containing metal powder containing zinc, and inorganic binder. A corrosion-proof layer having excellent anti-fouling property, rust-proofness, and adhesiveness is formed on the base iron with a double-layered coating film formed by superposing the zinc-containing corrosion-proof coating film having the sacrificial corrosion prevention effect of zinc on the galvanized coating film.
