A masterbatch manufacturing method is disclosed in which carbon black is added to a liquid and this is agitated to obtain a carbon black slurry; the carbon black slurry and rubber latex are mixed to obtain pre-coagulation rubber latex; and the pre-coagulation rubber latex is coagulated; wherein, at the operation in which the carbon black slurry is obtained, dispersion time from the start of agitation to the end of agitation is not less than 5 times, but not greater than 40 times. A particle diameter reduction relaxation time v may be found by plotting measurement results on a planar graph in such fashion that elapsed time t (minutes) since the start of agitation is plotted on the horizontal axis, and particle diameter f (μm) of carbon black is plotted on the vertical axis, to obtain a best-fit solution.
