PROBLEM TO BE SOLVED: To provide a method for producing a thermosetting resin coating film which has uniform periodic uneven structure on the surface without adding particles of a different kind and without surface treatment after forming the coating film and the coating film obtained by the method. SOLUTION: In the method, a uniform solution comprising the thermosetting resin (A), a solvent (B) which dissolves the resin, and a poor solvent (C) for the resin is prepared, after the solution being applied on a base material, at least part of the thermosetting resin is subjected to phase separation while the solvent and the poor solvent are evaporated, and the resin is dried and heat-treated. The coating film obtained by the method is provided.
