PROBLEM TO BE SOLVED: To provide a powder molding method where variation in the weight of a molded body in powder molding is suppressed so as to achieve the improvement in the reliability of a product and the improvement in a yield represented by sintered parts. SOLUTION: In powder molding where raw material powder P filled into the cavity 4 of a die 1 is subjected to compression molding by upper and lower punches 3, 2, the temperature of a powder feed box 11 feeding the raw material powder P is controlled so as to hold the temperature of the raw material powder P filled into the cavity 4 to the prescribed one, and, in this state, continuous molding for the powder is performed.
