To provide a novel fluorinated aromatic compound having at least two carbon-carbon unsaturated bonds, a method for its production, a curable material comprising the fluorinated aromatic compound, a cured product thereof, and an optical member. The fluorinated aromatic compound is represented by formula (A), wherein n is an integer of 0 to 6, a is an integer of 0 to 5, b is an integer of 0 to 4, c is an integer of 0 to 4, a+c+n is 2 to 6, a+b is 2 to 9, Z is a single bond, —O—, —S—, —CO—, —C(CH 3 ) 2 —, —C(CF 3 ) 2 —, —SO—, or —SO 2 —, Rf 1 is a C 1-8 fluoroalkyl group, Y 1 and Y 2 are each independently a group represented by formula (1) (s is 0 or 1, and R 1 , R 2 , R 3 , and R 4 are each independently a hydrogen atom or a fluorine atom), and F in the aromatic ring indicates that hydrogen atoms in the aromatic ring are all substituted by fluorine atoms. |
