PROBLEM TO BE SOLVED: To provide a compression molded product reduced in the density difference in a mold, its manufacturing method and to provide a sintered body reduced in the occurrence of dimensional failure or deformation obtained by baking the compression molded product. SOLUTION: In the manufacturing method of the compression molded product having a ring forming part for forming a ring shape and the inner leg part connecting a part of the rining forming part and another part in a ring and characterized in that the cross-sectional shape of the inner leg part is different from that of the ring forming part, a molding protruded part is pushed in the powder filling recessed part filled with the powder material. At the time of compression molding, a part of the powder material housed in the first recessed part forming the inner leg part is allowed to escape from the first recessed part.
