A method for producing a rubber wet masterbatch comprises step (i) of producing a slurry solution by dispersing carbon black in a dispersing solvent in the presence of an inorganic filler, step (ii) of producing a slurry-containing rubber latex solution by mixing the slurry solution with a rubber latex solution, and step (iii) of producing a rubber wet masterbatch by solidifying and drying the slurry-containing rubber latex solution. The inorganic filler has a Mohs hardness of 5 or more, and in the step (i), the amount of the inorganic filler added is less than 50% by mass where the amount of the carbon black added is 100% by mass.
