A polymer containing a recurring unit having an aliphatic polycyclic structure, wherein at least two atoms constituting the ring skeleton of the aliphatic polycyclic structure constitute the main chain of the polymer, and the recurring unit has an aliphatic ring containing a sulfonyl group as the constitutive group of the ring skeleton, has high refractivity, high Abbe's number, high-level heat resistance, high-level light transmittance and low water absorption.
