Provided is an additive for an optical resin including a (meth)acrylate compound represented by general formula (1) below: [in general formula (1), each X independently represents a fluorine atom or a methyl group in which at least one hydrogen atom is substituted with a fluorine atom; m represents an integer of 0 to 5; Rrepresents an alkylene group or an oxyalkylene group having a carbon number of 1 to 8; and Rrepresents a hydrogen atom or a methyl group].

(Meth)acrylate compound, additive for optical resin, optical element, and optical device

Low refractive index and high dispersion material which can produce a bonded-multilayer DOE having an excellent optical performance is obtained, and the optical member using this is obtained. The resin precursor for optical materials obtained through the addition reaction of the composite containing a di (meth) acrylate shown in the following Chemical Expression 1.
