Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a thermoplastic resin material undergoing a very small change in refractive index by temperature fluctuation and an optical element using the same. SOLUTION: The thermoplastic resin material comprises a host material comprised of an organic polymer and, dispersed therein, semiconductor fine particles, and has an absolute value ¾dn/dT¾ of the rate of change of the refractive index n to the temperature T satisfying the condition prescribed by the formula (A): 0≤¾dn/dT¾≤5.0×10-5.
