The present invention has its object to provide a thermoplastic resin for producing moldings having enough transparency and excellent in permanent antistatic properties and mechanical properties. The present invention provides a transparent resin composition which comprises at least one block polymer (A) selected from the group consisting of specific block polymers (A1) and (A2) and a transparent resin (B), with the difference in refractive index between (A) and (B) being not more than 0.01.
