Discharge device and hair care device

A discharge device comprising:

• a discharge electrode;
• a counter electrode that faces the discharge electrode in a first direction;
• and
• a voltage application unit that applies an application voltage between the discharge electrode and the counter electrode to generate a discharge, wherein
• the counter electrode includes:
• a dome-shaped electrode recessed to a side opposite to the discharge electrode in the first direction, and
• a protruding electrode that protrudes in a second direction intersecting the first direction from an opening edge of an opening of the dome-shaped electrode, the opening being provided at an end opposite to the discharge electrode,
• the discharge device forms a discharge path having at least partial dielectric breakdown between the discharge electrode and the protruding electrode when the discharge occurs,
• the discharge path includes:
• a first dielectric breakdown region generated around the discharge electrode, and
• a second dielectric breakdown region generated around the protruding electrode,
• a shape of each of the plurality of the protruding electrodes when viewed in the first direction is a triangle, and
• a base of the triangle is longer than a perpendicular line from a vertex facing the base to the base.
