PROBLEM TO BE SOLVED: To provide a method for producing an un-granulated carbon black-containing wet master batch, by which the carbon black-containing master batch capable of improving the reinforcing property, abrasion resistance, and the like of a rubber and good in handleability and kneadability can efficiently be produced. SOLUTION: This method for producing the un-granulated carbon black-containing wet master batch is characterized by having (a) a process for preparing a mixture liquid of a rubber component-containing rubber solution with a carbon black-dispersed slurry liquid, (b) a process for coagulating the mixture liquid and taking out the formed coagulation, and (c) a process for drying the taken coagulation, wherein the carbon black-dispersed slurry liquid in the process (a) is an un-granulated carbon black-dispersed slurry liquid.
