PROBLEM TO BE SOLVED: To provide a method and equipment for manufacturing a bonded magnet, capable of smoothly filling the forming space of a forming die with a kneaded material of magnetic powder and a liquid binder resin, free from dispersion of the amount of filling, and capable of providing a bonded magnet having excellent dimensional accuracy. SOLUTION: The forming die is provided with dies 12, 14 having a filling-side punch 20 and a pressing-side punch 36, respectively. The filling-side die 12 is filled with a kneaded material of magnetic powder and a liquid binder resin, and the kneaded material is compressed using the pressing-side punch 36 to form a bonded magnet. The filling-side punch 20 of the die is excitably provided by being wound with an exciting coil 30 and also is slidably provided with respect to a die 18 of the die and can form a forming space. When the die is filled with the kneaded material, the filling-side punch 20 is excited and the kneaded material is magnetically attracted to the filling-side punch 20.
