An ion generating device () includes discharge electrodes () each having a plurality of electrically conductive members () which form respective tip surfaces (). A longer dimension direction of the tip surfaces () is nonparallel to an air sending direction (A). This allows for efficient release of ions.

Ion generating device and method for manufacturing ion generating device

A discharge device capable of maintaining a stable discharge performance even in a highly humid environment or an atmospheric environment containing salt includes a discharge electrode discharging when a voltage is applied thereto, a substrate supporting the discharge electrode, an induction electrode arranged apart from the discharge electrode, and an insulator enclosing all of the substrate and the induction electrode. The discharge electrode has a root portion supported by the substrate, a pointed end protruding from a surface of the insulator, and a taper portion tapering from the root portion toward the pointed end. An outer peripheral surface of the root portion is made of a material having an ionization tendency lower than that of hydrogen.
