PROBLEM TO BE SOLVED: To provide a feeder for powder molding capable of uniformly packing raw material powder into a cavity, and to provide a method of feeding raw material powder for powder molding. SOLUTION: In the feeder 11 for powder molding moving back and forth on a die 3 and packing raw material powder P into a cavity 7 of the die 3, a feeder body 12 capable of moving on the die 3 back and forth, a raw material powder feed tube 13 connected to the posterior part of the feeder body 12, a leveling member 21 of leveling the raw material powder P in the feeder body 12, and a driving means 22 of driving the leveling member 21 to back and forth direction are equipped. By leveling the raw material powder P in the feeder body 12 with the leveling member 21, the raw material powder P can be uniformly packed into the cavity 7, and a sintered product having reduced variation in density can be obtained.
