[PROBLEMS] To efficiently and stably produce polycarbonate resin pellets or polycarbonate resin films having excellent optical characteristics, thermal stability, hue, and mechanical strength, and having few foreign substances. A polycarbonate resin obtained by polycondensation of a dihydroxy compound and a carbonic acid diester is filtered using a filter and then cooled and solidified, wherein the dihydroxy compound contains a specific dihydroxy compound. At least, the filter has an opening of 50 μm or less, and is filtered so that the temperature of the resin after filtration using the filter is 200 ° C. or higher and lower than 280 ° C.
