Abstract
Discharge device includes discharge electrode, voltage application circuit, and current limiting element. Discharge electrode is disposed to face counter electrode, and retains liquid. Voltage application circuit is electrically connected to discharge electrode and counter electrode with discharge electrode as a ground side. Voltage application circuit generates discharge between discharge electrode and counter electrode by applying a voltage between discharge electrode and counter electrode. Current limiting element is electrically connected to a side of discharge electrode opposite to counter electrode. Current limiting element limits a current flowing to discharge electrode.
