This droplet discharge device, which is provided with a discharge path (12) the tip of which constitutes a discharge opening (11), a plunger (30), a liquid chamber (50) through which a plunger (30) passes, a plunger drive mechanism that moves the plunger (30) forward and back, and a plunger position determining mechanism that determines the position of the tip part of the plunger (30), discharges liquid material in a droplet state by applying inertial force to the liquid material by forward movement of the plunger (30) in a state in which the tip part of the plunger (30) does not contact the inside wall of the liquid chamber (50). This droplet discharge device and droplet discharge method using that device push an amount of the liquid material necessary to form a desired droplet out of the discharge opening (11) by making the plunger (30) move forward and form a droplet of a minute amount by shedding the liquid material pushed out of the discharge opening (11) by making the plunger move back thereafter. |
