A ring molded article manufacturing method comprising: a step (S1) of performing first forging on a material such that the material is formed in a shape including a bottom which is formed in a disk shape, and a peripheral wall which is inclined to a direction from a center of the bottom toward an outer periphery thereof, in a direction from an outer periphery of the bottom toward one side in a direction of a center axis of the bottom ; a step (S2) of drilling the bottom of a first forged article obtained by the step (S1) of performing the first forging; a step (S3) of ring-rolling a drilled article obtained by the step (S2) of drilling; and a step (S4) of producing a ring molded article in which a ring material obtained by the step (S3) of ring-rolling is placed inside two molds , the ring material is then processed by second forging so as to be pressed by the two molds in a direction of a center axis of the ring material , and the ring molded article is thus produced, the ring molded article manufacturing method charaterised in that in the step (S1) of performing the first forging, if a one half section of the peripheral wall is divided into a one side region and an another side region in the direction of the center axis of the first forged article based on a middle of a maximum height (h1) of the first forged article in the direction of the center axis of the first forged article , a straight line passing through a center of gravity of the one side region and a center of gravity of the another side region is inclined by an angle (θ1) relative to the center axis of the first forged article , of which a range is 7 degrees to 40 degrees. a step (S1) of performing first forging on a material such that the material is formed in a shape including a bottom which is formed in a disk shape, and a peripheral wall which is inclined to a direction from a center of the bottom toward an outer periphery thereof, in a direction from an outer periphery of the bottom toward one side in a direction of a center axis of the bottom ; a step (S2) of drilling the bottom of a first forged article obtained by the step (S1) of performing the first forging; a step (S3) of ring-rolling a drilled article obtained by the step (S2) of drilling; and a step (S4) of producing a ring molded article in which a ring material obtained by the step (S3) of ring-rolling is placed inside two molds , the ring material is then processed by second forging so as to be pressed by the two molds in a direction of a center axis of the ring material , and the ring molded article is thus produced, the ring molded article manufacturing method charaterised in that in the step (S1) of performing the first forging, if a one half section of the peripheral wall is divided into a one side region and an another side region in the direction of the center axis of the first forged article based on a middle of a maximum height (h1) of the first forged article in the direction of the center axis of the first forged article , a straight line passing through a center of gravity of the one side region and a center of gravity of the another side region is inclined by an angle (θ1) relative to the center axis of the first forged article , of which a range is 7 degrees to 40 degrees. <EOS>
