Provided is a discharge device that can improve the efficiency of generating reactive species. The discharge device includes a discharging unit, which has a tip end and discharges from the tip end in response to an application of a voltage, an induction electrode, which forms an electric field between the induction electrode end the discharging unit, and a second electrode, which is disposed between the discharging unit and the induction electrode and receives a voltage having a polarity the same as a polarity of the voltage applied to the discharging unit.
