Abstract: A gas mixing apparatus includes: a discharge port of gas provided near conduit space through which the high-viscosity material can flow; a piston pump including a cylinder that can communicate with the conduit space through the discharge port, a piston arranged inside the cylinder, and a drive device for moving the piston between a top dead center and a bottom dead center inside the cylinder; a discharge valve that opens and closes the discharge port; and a suction valve that opens and closes a suction port of the gas into a cylinder space, in which the cylinder forms the cylinder space having a predetermined volume when the piston is located at the top dead center, and in which a tip of the piston approaches the discharge port when the piston is moved toward the bottom dead center.
