Abstract
A cylinder that kneads an injection material, a heat insulating cover that covers a side surface of the cylinder, the heat insulating cover including a first end portion and a second end portion, a heater arranged between the heat insulating cover and the cylinder, the heater heating a first region of the cylinder, and a first heat pipe that thermally connects the first region and a second region to each other, the second region being different from the first region, are provided. The heat insulating cover includes the first end portion and the second end portion through which the injection material passes, and the first region is closer to a midpoint between the first end portion and the second end portion than the second region.
