PROBLEM TO BE SOLVED: To provide a resin pellet mixture which does not sublimate in the production of a masterbatch, scarcely stains molds, and has excellent heat- resistant stability, and to provide a method of producing the resin pellet mixture, by which molded articles having good hues can be obtained. SOLUTION: In has been found that this resin pellet mixture which does not sublimate in the production of a masterbatch, scarcely stained molds, and has excellent heat-resistant stability is obtained by using a masterbatch containing the combination of a hindered phenol-based antioxidant with a phosphite-based antioxidant. And also, it is found that the resin pellet mixture having a good hue can be produced by using polybutylene terephthalate pellets having a specific water content in the production of the masterbatch.
