PROBLEM TO BE SOLVED: To provide a method for producing regenerated fibrous filler-reinforced polyphenylene sulfide granules by which used molded products or mill ends made of fibrous filler-reinforced polyphenylene sulfide, which are discarded so far without reusing, can be reused as a raw material for electric or electronic parts, automotive parts or the like without discarding. SOLUTION: The method for producing regenerated fibrous filler-reinforced polyphenylene sulfide granules includes supplying pulverized powder of molded products made of fibrous filler-reinforced polyphenylene sulfide to a single screw extruder with a full flight screw having a compression ratio of 1.5-3 or to a twin screw extruder with conical twin screws, and carrying out extrusion granulation in a temperature range of 270-320°C.
