PROBLEM TO BE SOLVED: To provide a material force-feeding system which can perform suction of a resin material without wastes. SOLUTION: This material force-feeding system 10 is constituted by providing an approximately cylindrical buffer tank 12 having bottom, a pressure-feeding means 17, and a material-replenishing device 18. In this case, in the buffer tank 12, a resin material M of a high viscosity such as a silicone is housed. The pressure-feeding means 17 sucks the resin material M in the buffer tank 12 and pressure-feeds to a nozzle 15 side. The material replenishing device 18 feeds the resin material M for a replenishment to the buffer tank 12. The material replenishing device 18 pushes out the resin material M for the replenishment, which is housed in a material container 33, to the buffer tank 12 side when the residual amount of the resin material M in the buffer tank 12 has become a specified amount.
