A liquid material discharge device that can remove bubbles in a liquid material to achieve a stable discharge amount of the liquid material and where a plunger section is reduced in weight. The liquid material discharge device has a liquid material supply section for supplying the liquid material to be discharged, a measuring section having a measuring hole and a plunger sliding on the inner wall surface of the measuring hole to suck the liquid material into the measuring hole and discharge it, a discharge section having a discharge opening for discharging the liquid material, a valve section for changing over the communication between the measuring section and the liquid supply section or the communication between the measuring section and the discharge section, and a debubbling mechanism provided in a flow path running from the liquid supply section to the measuring section. The debubbling mechanism has a first flow path (4) communicating with the liquid material supply section side, a second flow path (5) communicating with the measuring section side, and a body (3) for making the first flow path and the second flow path communicate with each other and having a greater width than the first flow path. A discharge opening of (6) of the first flow path is located above a suction opening (7) of the second flow path. |
