A production method for a rubber wet master batch, the method comprising: a step (I) for adding and mixing a concentrated latex solution and a field latex solution to a carbon black-containing aqueous slurry solution obtained by dispersing carbon black in water, to produce a carbon black-containing aqueous rubber latex solution; a step (II) for allowing the resultant carbon black-containing aqueous rubber latex solution to coagulate, to produce a carbon black-containing rubber coagulation; and a step (III) for hydrating and drying the resultant carbon black-containing rubber coagulation, to produce a rubber wet master batch, wherein in the step (I), the mass ratio of the rubber component of the concentrated latex solution and the rubber component of the field latex solution (the rubber component of the concentrated latex solution/the rubber component of the field latex solution) is not more than 1. The production method for a rubber wet master batch provides a vulcanized rubber having excellent low-exothermicity and reinforcement properties.
