PROBLEM TO BE SOLVED: To provide a mold apparatus for segment magnets which can enhance the parallelism of magnetic fields and permits the uniformity of orientation. SOLUTION: The mold apparatus for the segment magnets molds the molded goods of the segment magnets by packing powder for molding a magnet material into a cavity 12 of a die 11 consisting of a nonmagnetic member, orienting the powder for molding the magnet material under application of the magnetic field thereto and pressing the powder by an upper punch 13 and lower punch 14 consisting of a ferromagnetic member in the same direction as the direction of the magnetic field, in which first and second magnetic field correcting members 18 and 19 consisting of a ferromagnetic material are respectively arranged near the cavity 12 at both end faces in the direction of the magnetic field of the die 11.
