PROBLEM TO BE SOLVED: To obtain the subject molded product free from separation of each pellet, excellent in color tone and usable for injection molding, extrusion molding and blow molding by blending a colored master resin pellet with a base resin pellet and molding the blended matter thereafter. SOLUTION: This molded product is produced by blending a colored master resin pellet having a sheath-core structure (A) with a base resin pellet (B) and molding the blended matter. The component A has the sheath-core structure arranging a desired master colored resin at the core part and the base resin at the sheath part, and preferably the volume of the core part is within three times of the volume of the sheath part. For example, an extruder 2 can be connected using an adaptor to inlet 1 for the base resin constituting the sheath part and extruder 4 can be connected using an adaptor to inlet 3 for the colored master resin constituting the core part. The colored master resin pellet can be produced by extruding both resins in the state of a strand so as to form the sheath-core structure under a desired condition, cooling the strand, cutting the strand and the like.
