A process for producing an unvulcanized rubber composition comprising a rubber wet master batch yielded by using, as raw materials, at least a filler, a dispersing solvent and a rubber latex solution, the rubber latex solution comprising two or more rubber latex solution species different from each other, and the process comprising a step (I) of dispersing the filler into the dispersing solvent to produce a filler-containing slurry solution, a step (II) of mixing the filler-containing slurry solution with the rubber latex solution to produce a filler-containing rubber latex solution, and a step (III) of coagulating and drying the filler-containing rubber latex solution to produce the rubber wet master batch.
