Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a perfluoro group-containing (meth)acrylate serving as a component for forming an optical material having a low refractive index and excellent in mar resistance, heat resistance and chemical resistance. SOLUTION: This perfluoro group-containing (meth)acrylate is represented by formula (I): (CpFq-O-)r-A-(-O-CO-CR=CH2)s[wherein (p) is 1 to 18; (q) is 3 to 37; (r) is an integer of 1 to 18, and (s) is an integer of 2 to 19, provided that r+s=(3 to 20); A is a dehydroxylation residue of a polyhydric alcohol; and R is H or methyl].
