ABSTRACT:
The present invention is to provide a polymerizable compound which can be a raw material for a resin having high transparency, good heat resistance and mechanical strength required for optical components such as plastic lenses and the like, while attaining a high refractive index (nd) exceeding 1.7, and an optical component composed of such a resin.Disclosed is a compound represented by the general formula (3),wherein, in the formula, M represents a metal atom; X1and X2each independently represent a sulfur atom or an oxygen atom; R1represents a divalent organic group; m represents an integer of 0 or 1 or more; p represents an integer of from 1 to n; q represents an integer of from 1 to (n−p); n represents a valence of a metal atom M; Yq each independently represent an inorganic or organic residue; and when q is 2 or more, Yq may be bonded to one another for forming a ring structure with the intermediary of a metal atom M.
