PROBLEM TO BE SOLVED: To provide a heat-resistant ferritic steel that is surface-treated with a surface-treating method for steel, which is inexpensive and simple and can improve the water-vapor oxidation resistance. SOLUTION: A substrate has a film of a Cr oxide on its surface, which is formed by depositing Cr on the substrate with shot-peening treatment using a shot material of powdery Cr and preliminarily oxidizing the Cr.
