PROBLEM TO BE SOLVED: To provide a coating film for coil coating use having excellent adhesivity and thermal shock resistance, etc., suitable for effectively preventing the damage of a rotor coil of e.g. a power tool motor caused by foreign material. SOLUTION: The objective coating film for coil coating use is produced by curing a composition containing an epoxy component composed of (A) 50-100 wt.% of a bisphenol-type epoxy resin and (B) 0-50 wt.% of a urethane-modified epoxy resin having chelate-forming property and, based on 100 pts.wt. of A+B, (C) 3-15 pts.wt. of a latent curing agent such as dicyandiamide, (D) 0.5-10 pts.wt. of a cure accelerator such as toluenebisdimethylurea, (E) 1-200 pts.wt. of an inorganic filler such as calcium carbonate and (F) 3-10 pts.wt. of a thixotropic agent such as fine silica powder.
