The invention relates to a thermosetting resin composition comprising (A) 20 to 90 mass % of thermosetting resin, (B) 10 to 80 mass % of inorganic and/or organic fine particles and (C) 0.1 to 5 mass % of fluorine-containing polyether, wherein (C) is polymer having fluorinated alkyl polyoxetane structure of formula (1) or (2), n n n n n n n n n n (m is an integer of 1 to 100, n is an integer of 1 to 6, R 1 represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, R 2 and R 3 each represent a straight or branched chain alkyl group having 1 to 20 carbon atoms, with a proviso that at least 50% of hydrogen atoms present in the alkyl group is substituted by fluorine and the other hydrogen atoms are substituted by hydrogen, iodine, chlorine or bromine atoms) or a composition containing copolymer which consists of monomer having fluorinated alkyl polyoxetane structure and oxygen-containing monomer having 2 to 6 carbon atoms. |
