Abstract: A polycarbonate-polyorganosiloxane copolymer comprises a polycarbonate block (A-1) formed of a repeating unit with a specific structure and a polyorganosiloxane block (A-2) containing a repeating unit with a specific structure. A difference between the haze value (haze A) after retention for 3 minutes and the haze value (haze B) after retention for 20 minutes, of the polycarbonate-polyorganosiloxane copolymer or a resin composition thereof at 300° C. or 340° C., Δhaze, is less than 0.4.
