Abstract: PURPOSE: A polycondensation resin manufacturing method is provided to efficiently prepare a polycondensation resin that is not damaged by fusions between lower order condensates themselves or scaling in a pipe of the lower order condensates. CONSTITUTION: A polycondensation resin manufacturing method including a process of solid polymerizing a lower order condensate, wherein the method comprises the following steps of: preparing a lower order condensate; press-molding the obtained lower order condensate to obtain a granular compressive molding body; and solid polymerizing the granular compressive molding body. The solid polymerizing of the granular compressive molding body is performed in a vertical tower type device or a vertical tower type machine. The polycondensation resin is polyamide, polycarbonate, or polyester. A compression pressure of the press-molding is 10-800 MPa.
