ます。 [Scope of Claim for Utility Model Registration] 1. A sprue bush that contacts the nozzle tip of an injection molding machine and/or constitutes a molten resin passage through which molten resin is injected from the nozzle of the injection molding machine into a cavity formed in a mold. Alternatively, in a sprue bush including a gate portion connecting a molten resin passage and a cavity, the sprue bush is constituted by an inner sprue bush having a molten resin passage and an outer sprue bush containing the inner sprue bush, and the inner and outer sprue bushes A sprue bushing characterized in that a space provided between the two is evacuated to a high degree of vacuum, and a vacuum heat insulating layer is formed adjacent to an outer peripheral wall surface of at least a portion of the molten resin passage. 2. The sprue bushing according to claim 1, wherein the pressure in the space is reduced to 10 −5 mmHg or less. The brief description of the drawing has been amended as follows. Insert "B...secondary sprue bushing" between the fifth line and the sixth line from the bottom of page 15 of the specification.
