To provide an apparatus and a method for powder molding capable of manufacturing a green compact which does not damage a wire.

In the powder molding apparatus 1, the green compact is manufactured by molding an outer peripheral face 50c of a powder molded body 50 with an inner peripheral face 2c of a frame die 2; molding a first face 50a of the powder molded body 50 with an end face 4a of a bottom die 4; and molding a second face 50b of the powder molded body 50 with the end face 14a of the top die 14; further molding an open edge on the first face 50a side of the powder molded body 50 with a slanted peripheral face 10a of a first inside die 6, and molding an open edge on the second face 50b side of the powder molded body 50 with a slanted peripheral face 20a of a second inside die 16. The peripheral faces 10a and 20a are slanted tapering toward a through hole of the frame die 2. Thus, formation of a tapered face 50e in the open edge of the through hole 52 can be performed in advance, where chamfering by a barrel polishing method is very difficult to apply.
