PURPOSE: To simply repair the flaw part of a film by a method wherein a solid coating material capable of forming a film fixed to a sheet having specific surface tension in a lumpy state in a releasable manner pressed and transferred to the minute recessed part formed to the surface of the film by removing a minute film flaw part and cured.
CONSTITUTION: Processing laser is applied to a minute film flaw part caused by dust or an oil droplet to remove the film flaw part along with the dust or oil droplet to form a minute recessed part 8 to the surface of a film. Thereafter, the solid coating material 16 (e.t., two-pack type paint composed of a polyol resin/polyisocyanate compound system) capable of forming a film fixed to the single surface of a sheet 15 (e.g., fluororesin sheet) having surface tension of 10-60 dyne/cm in a lumpy state in a releasable manner is pressed and transferred to the minute recessed part 8 and cured. As a result, the film flaw part can be simply repaired without requiring labor and a time and a lowering of the film capacity of the repaired part is not almost generated.
