A discharge device includes a discharge member, a support portion, and a protruding piece. The discharge member discharges when a voltage is applied thereto. The support portion has a flat-plate shape and supports the discharge member. The protruding piece is inclined relative to the support portion and protrudes in a direction intersecting the support portion. The support portion preferably includes a holding portion that holds the discharge member. The discharge member is preferably a bundle of fibers. The support portion preferably includes a pair of first surfaces. The holding portion preferably holds the discharge member on one first surface of the pair of first surfaces. The protruding piece is preferably inclined, relative to the support portion, in a direction in which the discharge member is located.

Discharge device

An ion generation device includes a discharge electrode substrate, an induction electrode substrate, and an insulating resin. The discharge electrode substrate on which a discharge electrode is mounted and a first electrode connected to the discharge electrode is formed. The induction electrode substrate on which an induction electrode configured to generate a discharge between the induction electrode and the discharge electrode and a second electrode connected to the induction electrode are formed. The insulating resin is filled at least between the discharge electrode and the induction electrode. The insulating resin provides insulation between the discharge electrode and the induction electrode. The first electrode and the second electrode are disposed and face each other at least partially. The first electrode, the second electrode, and the insulating resin interposed between the first electrode and the second electrode form a capacitor.

Ion generation device, discharge substrate, and electronic device

Provided is a discharge device that can improve the efficiency of generating reactive species. A discharging unit that discharges in response to an application of a voltage protrudes from a housing. The discharging unit is disposed in a duct through which gas flows. An upstream support is disposed upstream of the discharging unit in a direction of gas flow without overlapping the discharging unit. The upstream support protrudes further from the housing than the discharging unit. The upstream support includes a root portion joined to the housing. The root portion includes a widened portion that is disposed in the duct and that protrudes toward the discharging unit when viewed in the direction of gas flow.
