    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.

    Abstract: Provided is a polycarbonate-polyorganosiloxane copolymer, including a specific polycarbonate block unit (A) and a specific polyorganosiloxane block unit (B), in which in a differential molecular weight distribution curve obtained from measurement of the polyorganosiloxane block unit (B) by gel permeation chromatography using the polystyrene calibration curve, the curve having an axis of abscissa indicating a logarithmic value log(M) of a molecular weight M and an axis of ordinate indicating dw/d log(M) obtained by differentiating a concentration fraction w with respect to the logarithmic value log(M) of the molecular weight, (1) a dw/d log(M) value becomes maximum in a range of 3.4≦log(M)≦4.0, and (2) in the differential molecular weight distribution curve, a ratio of a value obtained by integrating the dw/d log(M) value over a range of 4.0≦Log(M)≦4.5 to a value obtained by integrating the dw/d log(M) value over the entire range of the log(M) is 6% or more and 40% or less.
