A liquid material discharge device that can discharge a liquid material supplied to the device with the material kept clean, whose amount of discharge is stabilized, and that can be reduced in size. The liquid material discharge device has a liquid material supply section for supplying a liquid material to be discharged, a discharge section having a discharge opening for discharging the liquid material, a measurement section consisting of a measurement hole and a plunger for sucking the liquid material into and discharging it from the measurement hole by sliding on the inner wall surface of the measurement hole, a valve section consisting of a body and a valve body, the valve body having a channel that interconnects the liquid material supply section and the measurement section and a channel that interconnects the measurement section and the discharge section and sliding in a space provided in the body, and a control section for controlling the sections above. To suck the liquid material into the measurement hole, the control section positions the valve body at a first position to interconnect the liquid material supply section and the measurement section and to interrupt the connection between the measurement section and the discharge section. To discharge the liquid material contained in the measurement hole, the control section positions the valve body at a second position to interconnect the measurement section and the discharge section and to interrupt the connection between the liquid material supply section and the measuring section. |
