PROBLEM TO BE SOLVED: To provide a caulking material injector which can be miniaturized. SOLUTION: This caulking material injector is provided with a mounting part with thread formed at the outer peripheral surface, at the tip of a cartridge 10 charged with silicon. In the injector, a thread groove is formed on the opposite side to the tip part of a conical injection member 20, and the outer diameter of the tip part 30A of a cylindrical pressing member 30 is formed to be slightly smaller than the inner diameter of a body 11 of the cartridge 10. The thread of the mounting part of the cartridge 10 is screwed with the threaded groove of the injecting member 20 to mount the injection member 20 to the cartridge 10. A cap 40 is fitted to a receiving part 13 of the cartridge 10, and the cylindrical pressing member 30 is inserted and pushed in from the receiving part 13 to extrude silicon from the tip of the injection member 20.
