A method for forming a film includes the steps of: coating a surface of a steel material with an ultraviolet cured paint controlled to a predetermined control temperature; and then radiating the coated paint with ultraviolet rays to cure the coated paint to thereby form a film. When the surface of the steel material is coated with the ultraviolet cured paint, the surface temperature of the steel material is controlled within a range of -5°C to +20°C with reference to the control temperature, whereby a film having an even thickness distribution can be formed on the surface of the steel material. In this case, in order to make the thickness distribution of the film formed on the surface of the steel material evener and to prevent an irregular pattern from occurring the pattern being visually observed, to thereby make the appearance of the film good, it is preferable to control the surface temperature of the steel material within a range of 0°C to +10°C with reference to the control temperature. |
