The invention provides an extrusion device, a dehydration cylinder, a dehydration method and a manufacturing method of resin pellets. The problem to be solved is to prevent a dehydration cylinder from being discharged from a resin component while discharging moisture contained in a resin material from the dehydration cylinder. The invention provides an extrusion device which comprises a machine barrel. The screw rod is arranged in the machine barrel; and a dewatering cylinder body (11b) provided in the middle of the cylinder and discharging moisture separated from the resin material supplied into the cylinder. The dewatering cylinder body (11b) has a structure in which plate-shaped members (13) each having an opening through which a screw passes are arranged in the long axis direction of the cylinder. The surface roughness of the surfaces facing each other of the plurality of plate-like members (13) is greater than the surface roughness of the inner wall of the cylinder. 本发明提供了一种挤出装置、脱水用机筒、脱水方法以及树脂颗粒的制造方法。待解决
