PROBLEM TO BE SOLVED: To provide a method for manufacturing high-purity natural rubber particulates from a serous liquid obtained by centrifugalizing a natural rubber latex, easily and in a high yield. SOLUTION: A natural rubber latex or a deproteinized natural rubber latex is subjected to centrifugation. To a serous liquid thus obtained, a water-soluble polymer in an amount sufficient to phase-separate natural rubber particulates from the serous liquid, is added so that the natural rubber particulates are separated as a creamy component.
