PROBLEM TO BE SOLVED: To provide a fiber reinforced resin rotor having superior strength, impact resistance, and abrasion resistance and having high dimension accuracy and stability and to provide its manufacturing method. SOLUTION: A surface layer is formed of a sheet formed by impregnating thermosetting resin in reinforcing fiber, and a rotor tooth part is molded by filling a preparatory molding material obtained by kneading reinforcing short fiber with the thermosetting resin in a space between the surface layer and a central shaft. This constitution can reinforce the vicinity of the rotor surface by relatively long fiber chopped into the length 10-100 mm or continuous fiber and fill the space between the surface layer and the central shaft with the fiber reinforced resin.
