A method for producing a rubber-filler master batch wherein a rubber solution obtained by dissolving a diene rubber in an organic solvent is mixed into a slurry solution, which is obtained in advance by dispersing carbon black, silica and/or at least one inorganic filler represented by the following general formula (I): nM1?xSiOy?zH2O (I) [wherein M1 represents at least one selected from the group consisting of aluminum, magnesium, titanium, calcium and zirconium, oxides and hydroxides of such metals, hydrates thereof and carbonates of such metals, n, x, y and z respectively represent an integer of 1-5, an integer of 0-10, an integer of 2-5, and an integer of 0-10] in water, for forming a rubber-filler master batch. |
