A method for manufacturing a wet rubber masterbatch that will serve as raw material for vulcanized rubber having excellent tensile strength and tear strength and that will permit wet rubber masterbatch to be molded in a short time. A method comprising an operation in which a collection of granules comprising a plurality of granular coagula are obtained from a liquid mixture comprising filler and rubber latex solution, and an operation in which the collection of granules is compressed under conditions satisfying Formula I; 3≤P×Da≤500 (P indicates pressure (kgf/cm2) applied to the collection of granules. Da indicates granule diameter (mm) of the granular coagula), making it possible to cause a wet rubber masterbatch capable of serving as raw material for vulcanized rubber having excellent tensile strength and tear strength to be molded in a short time.
