PROBLEM TO BE SOLVED: To obtain a curing composition excellent in heat resistance, mechanical characteristics, electrical characteristics, weather resistance and storage stability by including an epoxy compound, a (meth)acryloyl compound and an amine compound. SOLUTION: This composition is prepared by including (A) an epoxy compound, (B) a (meth)acryloyl compound [e.g. diethylene glycol di(meth)acrylate] and (C) a catalytic quantity of an amine compound (e.g. 1,8- diazabicyclo[5.4.0]undecan-7-ene). The quantity ratio of the ingredient A to the ingredient B is set preferably in such a way that 0.6 to 1.7 equivalents of acryloyl group in the ingredient B based on one equivalent of epoxy group in the ingredient A is included. The ingredient C preferably has a basicity value of <=8 and its catalytic quantity preferably is 0.1-50 pts.wt. based on 100 pts.wt. of the ingredient A.
