The present invention provides a high refractive index linear polymer having a high refractive index, no coloring problems, and excellent moldability, workability and the like. A high refractive index linear polymer having a repeating unit represented by the following general formula (1). (In the formula, A and B represent a divalent organic group, X represents an oxygen atom, —NH—, or a sulfur atom, and D represents a thioalkylene group having 1 to 8 carbon atoms. 1) Two D and X in each may be the same or different.)
