The present invention is a method for producing a polycarbonate resin, comprising performing polycondensation through a transesterification reaction by using a catalyst and using a dihydroxy compound and a carbonic acid diester as raw material monomers, and feeding the produced polycarbonate resin to an extruder, wherein nthe dihydroxy compound contains at least a dihydroxy compound having a moiety represented by the following formula (1) in a part of the structure, nthe dihydroxy compound having a moiety represented by the following formula (1) contains a compound having a cyclic ether structure, and nthe temperature at the time of feeding the polycarbonate resin to the extruder is from 180°C to less than 250°C, n(with the proviso excluding the case where the moiety represented by formula (1) is a part of -CH 2 -O-H). n[Chem. 1] |
