The present invention relates to a screw, an emitting device and a pressure member (54). Cost of a screw (20) is reduced and quality of a molded product is improved. The rear end of the screw (20) is connected to a drive device. The screw has a screw head (61), backflow prevention device (62), and a plasticization member provided behind the backflow prevention device (62). The plasticization member has a screw body (52), a flight (53) formed projecting from the outer peripheral surface of the screw body (52), and a pressure member (54) formed adjacent to the backflow prevention device (62), in a predetermined area defined from the forward end of the screw body (52). The pressure member (54) has a smooth outer peripheral surface having an outer diameter greater than that of the screw body (52), so that the shape of the screw (20) can be simplified to reduce its cost and that a molding material stays at a reduced number of places.
