PURPOSE:To obtain easily a molding having a recess in the direction perpendicular to a pressurizing direction by providing a movable mold having a projecting part to a female mold, molding powder along the projecting part in the stage of pressurizing and moving the movable mold in the stage of taking out. CONSTITUTION:The raw material powder is packed into the female mold 14 and is compressively molded by moving an upper male mold 10 and a lower male mold 12 toward the center of the mold 14. The projecting part 20 of the mold 16 projects toward the inside of the mold 14 and the molding is executed along such projecting part. The mold 16 rotates and the projecting part 20 is contained in the mold 14 so that the notched surface 22 of the mold 16 forms the surface flush with the growing surface of the mold 14. the mold 10 moves upward and a lead wire 6 is drawn out. The mold 10 and the mold 12 move upward and the molding 14 is taken out. The lead wire 6 is cut in a suitable position and the molding 4 is transferred.
