PROBLEM TO BE SOLVED: To provide an injection device for a high temperature and high pressure reaction device capable of preventing plugging of a solid material and smoothly feeding a material to be injected. SOLUTION: This injection device is provided with a syringe part communicating with the high temperature and high pressure reaction device, a cylinder for injecting the material to be injected into the high temperature and high pressure reaction device via the syringe part, a piston having a through-hole in an axial direction and movably arranged in the cylinder, and a spindle which, provided at its tip with an injection object closure prevention part for insertion in the syringe part, penetrates in the through-hole of the piston and is movably arranged.
