<p>A device for discharging a constant amount of a high-viscosity material, capable of accurately discharging the material even if the material is sent under high pressure. A device for discharging a constant amount of a high-viscosity material, provided with: a discharge unit (400) having a discharge opening which discharges the high-viscosity material; a holding unit (300) having a holding area which holds the high-viscosity material, a receiving opening which supplies the high-viscosity material to the holding area, and a delivery opening which delivers the high-viscosity material to the discharge unit; and a high-pressure supply pump (100) for supplying to the holding unit under a first pressure the high-viscosity material having been filled into a container. A liquid sending unit (200) having a pump mechanism and a valve mechanism is provided in the flow path for connecting the high-pressure supply pump (100) and the holding unit (300), and the liquid sending unit sends the high-viscosity material to the holding unit by a second pressure adjusted to a lower pressure than the first pressure.</p> |
