Cured product, optical element, optical apparatus, and imaging apparatus

A cured product of a resin composition, the resin composition comprising:

• a compound represented by the following formula (1)
• wherein R1 to R5 are each independently selected from the group consisting of a polymerizable functional group, a substituted or unsubstituted alkyl group having 1 to 8 carbon atoms, a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms and having a polymerizable functional group at a terminal thereof, and a substituted or unsubstituted alkyl group having 2 to 6 carbon atoms and having a polymerizable functional group at a terminal thereof, in which one CH2 in a main chain is replaced by an oxygen atom or a sulfur atom,
• R5 to R9 are each independently selected from a hydrogen atom and a trifluoromethyl group, and
• at least one of R1 to R4 is a polymerizable functional group or a substituent having a polymerizable functional group, and at least one of R5 to R9 is a trifluoromethyl group.
