    • A resin composition suitable for an optical element in which the moldability, thermal resistance, mechanical strength, and low birefringence are not impaired, the deterioration is hardly generated although the laser light nearby the UV is used, change in the optical properties during the use are extremely small, particularly the light transmittance is maintained high, and a foreign substance is hardly deposited on a surface of the molded product such as an optical element. In addition, an optical element obtained by molding the resin composition, and an optical pickup device using the optical element. The thermoplastic resin composition contains the polymer having a specific structure and two kinds of specific optical stabilizers in a specific mass ratio among a hindered amine light stabilizer having the molecular weight of 400 to 5,000.
