PURPOSE:To obtain a resin magnet molding material which has good moldability, wherein ferrite can be filled at a high concn. and highly orientated, by kneading a ferromagnetic substance with a polyamide resin contg. a polyamide oligomer. CONSTITUTION:A ferromagnetic substance is kneaded with a polyamide resin contg. a polyamide oligomer as a matrix. When the polyamide oligomer is mixed with the polyamide resin, the rotational movement of the ferromagnetic substance is facilitated during injection molding in a magnetic field by the action of said oligomer so that the orientation ratio is increased. Further, the melt viscosity of the molding material is lowered, whereby the injection molding can be easily conducted. Even when the polyamide resin is in any form of pellet and powder, similar results can be obtd.
