PROBLEM TO BE SOLVED: To reduce an equipment cost and a production cost by enhancing operability and decreasing manufacturing processes and manufacturing apparatuses in a method for manufacturing a rubbery polymer by adding a coagulant solution to a cement-like polymer solution thereby coagulating a rubbery polymer component. SOLUTION: The manufacturing method of a rubbery polymer comprises a step for feeding a cement-like rubber solution and a coagulant solution to a pump with crushing functions to coagulate the rubbery polymer component thereby to obtain a crumb slurry containing a crumb-like rubbery polymer and a step for feeding the crumb slurry ejected from the pump with crushing functions directly to a screen and separating the rubbery polymer contained in the crumb slurry from the solvent and the coagulant solution through the screen.
