PROBLEM TO BE SOLVED: To provide an extruding device capable of reducing waste of viscous materials. SOLUTION: The device 10 has a plurality of extruding units 11 and 12 housing a high-viscosity material M, e.g. a silicone, and the units 11 and 12 can extrude the material M by applying a pressure to the material in each unit. In the device 10, a pressure is applied to the material M in the first extruding unit 11 to extrude; and, when the amount of the material M in the unit 11 decreases to a specified amount or smaller, a relatively small extruding pressure is also applied to the second unit 12 so that the reduction of the amount extruded from the unit 11 is made up with the material M extruded from the unit 12 in order to make a quantitative extrusion possible.
