PURPOSE:To improve the adhesion, uniformity and corrosion resistance of a ceramic film formed on the surface of a low carbon steel sheet or a stainless steel sheet by using a hollow cathode gun having a specified rate of ionization of an evaporated substance. CONSTITUTION:The surface of a low carbon steel sheet or a stainless steel sheet is cleaned and a ceramic film is formed on the surface by ion plating with a hollow cathode gun having >=50% rate of ionization of an evaporated substance. The ceramic film is made of one or more among nitride and carbide of one or more among Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Co, Ni, Al, B and Si and oxide of one or more among Al, Zn, Mn, Mg, Ti and Si. The adhesion of the ceramic film to the steel sheet, the uniformity and corrosion resistance can be improved by the increased rate of ionization.
