PROBLEM TO BE SOLVED: To provide a dispenser device and a bubble detection method capable of detecting bubbles on a liquid inside of a syringe where a plunger is disposed.SOLUTION: A dispenser device includes: a syringe 22 with which a nozzle 23 is provided at one side; a plunger 25 which is disposed inside the syringe 22 in contact with a liquid 27 that fills the syringe 22: a pressure application section which applies a pressure from another side of the syringe 22 into the syringe 22; plunger position detection sections 34, 35 which detect the position of the plunger 25; and a control section. The control section controls the pressure application section and determines the presence/absence of bubbles in the liquid 27 inside the syringe 22 based on signals outputted from the plunger position detection sections 34, 35. |
