A ring molded article manufacturing method comprising: a step 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 of drilling the bottom of a first forged article obtained by the step of performing the first forging; a step of ring-rolling a drilled article obtained by the step of drilling; and a step of producing a ring molded article in which a ring material obtained by the step of ring-rolling is placed inside two molds (16, 17), the ring material is then processed by second forging so as to be pressed by the two molds (16, 17) 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 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 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 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 of drilling the bottom of a first forged article obtained by the step of performing the first forging; a step of ring-rolling a drilled article obtained by the step of drilling; and a step of producing a ring molded article in which a ring material obtained by the step of ring-rolling is placed inside two molds (16, 17), the ring material is then processed by second forging so as to be pressed by the two molds (16, 17) 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 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 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.
