PROBLEM TO BE SOLVED: To provide a kneaded rubber manufacturing method capable of uniformly dispersing a filler throughout a rubber component when a kneaded rubber is produced in a continuous process and not causing a problem such as the deterioration of a work environment or the like due to the scattering of the powdery filler, and a rubber extruder used therein. SOLUTION: The kneaded rubber is manufactured by kneading at least the rubber component and the filler with each other. The rubber component is extruded into a tubular shape to form a tubular rubber 1 and this tubular rubber 1 is filled with the filler 2 to form a filler-sealed tubular rubber 3 which is, in turn, supplied to a continuous kneader to perform kneading. The rubber extruder 10 used in this manufacturing method is equipped with a cylindrical extrusion head 11 for extruding the rubber component into a tubular shape and a filler supply part 12 for supplying the filler 2 into the cylindrical extrusion head 11.
