A discharge device (1) includes a discharge head (10) that discharges a liquid material (50) from a nozzle opening (11) connected to the cavity (14) by varying the internal pressure of a cavity (14) using an actuator (6). The discharge head (10) includes a monitoring portion (12) provided between the cavity (14) and the nozzle opening (11) and the discharge device (1) further includes a detection apparatus (7) that detects the number and/or form of the particle-like bodies (51) included in the liquid material (50) in the monitoring portion (12) of the discharge head (10) and a control unit (74) that drives the actuator (6) according to the detection result (7a) of the detection unit (7) to change the state of the particle-like bodies (51) included in the liquid material (50) of the monitoring portion (12). |
