Provided is a molded resin body production method capable of suppressing resin deterioration during melt-extrusion. This molded resin body production method is characterized by comprising a step of passing resin through a resin inlet of a molding machine, which is equipped with the resin inlet, an extrusion machine, and a pressure adjustment device, in this order, to produce a molded resin body, wherein the resin pressure from the forward end portion of the extrusion machine to a resin suction inlet of the pressure adjustment device is 15.0 MPa or lower. |
