Abstract: To provide a method for manufacturing a bond magnet and a bond magnet manufacturing apparatus that can enhance the density.SOLUTION: When a bond magnet is manufactured, in a first compression-molding step ST1, magnetic powder M is compression-molded in a first cavity 61 by a first punch 70 to manufacture a cylindrical first molded body 11. Next, in a second compression-molding step ST2, the first molded body 11 is compression-molded in a second cavity 81 by a second punch 90 under a condition in which both the molding pressure and the molding temperature are increased, and a thermosetting resin coated with the magnetic powder M is cured to manufacture a cylindrical second molded body 12. Therefore, even when the density of the first molded body 11 is low, the second molded body 12 having a high density can be obtained. Further, in the second compression-molding step ST2, a step portion or the like is formed on the inner peripheral surface of the cylindrical first molded body 11.SELECTED DRAWING: Figure 2
