Discharge device having high-voltage circuit unit installed therein

摘要

A discharge device includes a dielectric, a first electrode and a second electrode arranged with the dielectric interposed therebetween, and a circuit unit to which the first electrode and the second electrode are electrically connected for generating a high voltage to be applied to the first electrode and to the second electrode. The dielectric is formed in a tube shape or a pipe shape having therein the circuit unit.
