PROBLEM TO BE SOLVED: To provide an integrally molded body capable of ensuring desired dimensional accuracy and high productivity. SOLUTION: This integrally molded body 10 is prepared by integrally molding a plurality of permanent magnet segments 12 disposed at equal intervals in an annular manner and a non-magnetic and non-conductive cylindrical member 14 disposed coaxially to the plurality of permanent magnet segments12 with a resin molding material 16. Preferably, the resin molding material 16 and the cylindrical member 14 are formed out of thermoplastic resin, and the inner-periphery surfaces of the permanent magnet segments 12 and the cylindrical member 14 are exposed and the outer-periphery surfaces of the permanent magnet segments 12 and the cylindrical member 14 are covered with the resin molding material 16.
