PROBLEM TO BE SOLVED: To provide a sulfur-containing heterocyclic compound capable of expressing high refraction index even if a know inexpensive resin is combined with a base resin.SOLUTION: A sulfur-containing heterocyclic compound is represented by a formula (1). (1), where each Ris a hydrogen atom, a substituted or unsubstituted aliphatic hydrocarbon group, a substituted or unsubstituted aromatic hydrocarbon group, a halogen atom, or a group represented by -R'-R. At least one of Ris the group represented by -R'-R. R' is a bivalent group represented by -S-, -S-S-, -S-S-S- or -S-R-S-. |
