Disclosed is a polymerizable compound which can be a raw material for a resin having high transparency, good heat resistance and mechanical strength required for optical members such as plastic lenses, while attaining a high refractive index (nd) exceeding 1.7. Also disclosed is an optical member composed of such a resin. Specifically disclosed is a compound having two or more thiol groups and an atom selected from metal atoms in a molecule. Also disclosed are a polythiol composition containing such a compound, a polymerizable composition containing such a polythiol composition, a resin obtained by polymerizing such a polymerizable composition, and an optical member composed of such a resin. |
