Abstract
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.
