And insulation between the discharge electrodes can be ensured. In addition, since the heat of the heat sink is transmitted to the protrusions and the protrusions are heated, the temperature of the air around the discharge electrode can be increased, the discharge electrode is likely to condense, and the amount of charged particulate water generated is increased. In addition, it is possible to reduce the power consumption required for condensation on the discharge electrode.
