Summary:PROBLEM TO BE SOLVED: To provide a method for producing a natural rubber capable of suppressing increase in viscosity during storing by adding a compound having a quaternary ammonium ion and a carboxyl ion in the molecule into a natural rubber latex and removing and drying water. SOLUTION: A producing method of a solid natural rubber is characterized in that a compound having a quaternary ammonium ion and a carboxyl ion in the molecule is added into a natural rubber latex and dissolved while stirring, and after that, dried without coagulating the natural rubber latex.
