A process for manufacturing multilayer pellets having a core-sheath structure with a molding material forming a sheath which covers the outer circumference of another molding material forming a core, which includes (a) supplying the core material and the sheath material to a die extruder having multiple extrusion-forming parts arranged along a circumference, (b) extruding multiple multilayer strands from the extrusion-forming parts by covering around the outer circumference of the core material concentrically with the sheath material, and (c) cutting the extruded multilayer strands to manufacture multilayer pellets.
