A discharge device for a liquid material containing solid particles, the discharge device comprising: a storage container in which the liquid material containing solid particles is stored; a measuring unit having a measuring hole into which the liquid material is filled; a plunger that is moved forward and backward in the measuring hole; a nozzle having a discharge port through which the liquid material is discharged; a selector valve having a first position at which the storage container and the measuring unit are communicated with each other, and a second position at which the measuring unit and the nozzle are communicated with each other; a plunger drive device that moves the plunger forward and backward; a selector valve drive device that changes over the first position and the second position of the selector valve; and a discharge control device including a processor and a memory in which a discharge control program is stored, wherein the discharge control program includes: a filling step of operating the selector valve to the first position, moving the plunger backward, and filling the liquid material into the measuring hole; an ejection step of operating the selector valve to the second position, moving the plunger forward, and discharging the liquid material in the measuring hole from the discharge port; an inflow step of operating the selector valve to the first position, moving the plunger forward, and causing the liquid material in the measuring hole to flow into the storage container; a discharge step of successively executing the filling step and the ejection step; and a stirring step of successively executing the filling step and the inflow step, characterized in that the discharge device further comprises a compressed gas source that is configured to supply a compressed gas under pressure adjusted by the discharge control device to the storage container through a tubing, that during the filling step, compressed gas under pressure adjusted by the discharge control device is supplied to the storage container, and that during the inflow step, compressed gas is not supplied to the storage container. a storage container in which the liquid material containing solid particles is stored;
