Abstract: A discharge device includes discharge electrode, counter electrode, and a voltage application device. Discharge electrode includes distal end portion. Counter electrode is disposed so as to face distal end portion of discharge electrode with a gap provided therebetween. The voltage application device applies a voltage between discharge electrode and counter electrode to generate a discharge between discharge electrode and counter electrode. Discharge electrode protrudes toward counter electrode. Counter electrode includes discharge portion where a discharge occurs between discharge portion and distal end portion of discharge electrode. Discharge portion extends along a circumference centered at distal end portion of discharge electrode.
