PROBLEM TO BE SOLVED: To provide a multipolar magnet body and a manufacturing method which significantly reduces a pitch between poles without being restricted by the pitch between the poles of a magnetized yoke. SOLUTION: A plurality of recesses 13 are formed at intervals on the surface of a structure 1 constituted of soft magnetic material, and permanent magnets 2 are formed by filling the recesses 12 with fluid permanent magnet members and positioning a magnetized surface 2a magnetized on the same magnetic pole on the surface of the structure 1. Moreover, a magnetic flux formed by the permanent magnet 2 induces a magnetic pole of a reverse polarity to the magnetic pole of the magnetized surface 2a of the permanent magnets 2 on the surface 12a of the structure 1 positioned between the adjacent permanent magnets 2.
