To obtain a new cycloaliphatic ester having two or three non-aromatic carbon rings each sharing two carbon atoms and a polymerizable unsaturated carboxylic acid acyloxy group bonded to the carbon atom on the junction.

This polymerizable cycoaliphatic ester is expressed by formula (1) or (2) (ring A, ring B, ring C, ring D and ring E are each a non-aromatic carbon ring, R is a polymerizable unsaturated group, Ra1, Rb1 and Rc1 are each same or different H, (protected) hydroxyl group or RCO2 (R is same to the above scribed)). The ring A, ring B, ring C, ring D and ring E are each a cyclopentane ring, a cyclohexane ring or a cross-linking ring. Vinyl group, isopropenyl group or allyl group are cited as the R.
