1. A polycarbonate resin, which is produced by using an end terminator comprising 3-pentadecylphenol obtained from a natural product, the polycarbonate resin having a YI value of 1.1 or less, where the YI value is measured by:
adding 500 ppm by mass of bis(2,6-di-t-butyl-4-methylphenyl)pentaerythritol phosphite to the polycarbonate resin to form a mixture, melting the mixture, kneading the mixture, and extruding the mixture with a vented single screw extruder of 40 mmφ at a resin temperature of 280° C. and a screw rotation speed of 100 rpm to obtain a pellet, molding the pellet into a molded article having a thickness of 3 mm, and measuring the molded article with a spectrophotometer by a transmission method at a measurement area of 30φ under a C2 light source. |
