The present invention aims to provide a method for producing a masterbatch with improved rubber physical properties such as tensile strength at break, rigidity, and fuel economy at high productivity by enhancing the amount of fillers incorporated into rubber and the dispersibility of fillers in rubber, as well as related products. The present invention relates to a method for producing a masterbatch, including: step (1) of mixing a rubber latex having a zeta potential of −100 to −20 mV with a filler dispersion having a zeta potential of −120 to −10 mV to prepare a latex compound; step (2) of adjusting the zeta potential of the latex compound obtained in step (1) to −30 to 0 mV; and step (3) of solidifying the coagulum obtained in step (2) with an organic solvent.
