The present invention relates to a liquid material discharge device, and can correspond to liquid material of different viscosity, and the structure the device does not protrude, or widened unnecessarily in the horizontal direction on the plunger forward and backward direction, the liquid material discharge device that allows concatenating a plurality of devices the challenge is to provide a a. The present invention provides a liquid material supply a liquid material supply port, valve block that includes a metering orifice and a liquid material supply port liquid material supply channel for communicating the nozzle which liquid ash discharge and ash mixture discharged charging and metering holes and the liquid material supply channel It communicates with the valve driving part 1 operate the flow path and the metering orifice and the change-over valve and a second flow passage communicating the nozzle, and the plunger to advance and retreat movement in the metering hole, and the plunger driving unit for driving a plunger, the switching valve which, as a liquid material discharge device which is constituted by transmission to forward drive of the valve driving the selector valve, the plunger driving section, the valve driving section, and provides a liquid material discharge device, it characterized in that the valve block extending in the direction of the length.
