PROBLEM TO BE SOLVED : To simplify a die structure, to improve the precision of the die, and to attain the smooth charging and forming of raw material powder.
SOLUTION : The forming device comprises : a die 1 having a forming space 1a penetrating in an almost horizontal direction; left and right punches 2, 3 inserted into the forming space 1a and movable in the horizontal direction with respect to the die 1; and magnetic field applying means (an upper coil 6 and a lower coil 7) of applying magnetic fields to the forming space 1a. Rare earth magnet raw material powder charged at the outside of the die 1 is introduced into the forming space 1a of the die 1 by the horizontal movement of the left and right punches 2, 3, and further, the rare earth magnet raw material powder is pressurized and formed in the horizontal direction by the left and right punches 2, 3. A compact 5 is moved in the horizontal direction in a state of being held by the left and right punches 2, 3, and is taken out from the die space.
