PROBLEM TO BE SOLVED: To provide a corrosion protection-covered steel material having durability over a long period by efficiently forming a dense film having sacrificial corrosion protection properties to the steel material, having excellent corrosion resistance and hardly having defects on a steel material, and to provide its production method. SOLUTION: The corrosion protection-covered steel material has a covering film formed by spraying the particulates of a metal or an alloy having sacrificial corrosion protection properties made into aerosol on the surface of a steel material. The metal or alloy having sacrificial corrosion protection properties is preferably includes one or more kinds selected from zinc, aluminum and magnesium. COPYRIGHT: (C)2007,JPO&INPIT
