Abstract
An ion generator configured to generate ions within a fluid passage that is at least partly defined by an electrical insulator may be provided with: a discharge electrode placed within the fluid passage; a ground electrode placed in a vicinity of the discharge electrode; a power source configured to intermittently apply a predetermined discharge voltage to the discharge electrode with respect to the ground electrode; and an antistatic electrode placed downstream relative to the discharge electrode within the fluid passage and to which a direct current voltage is applied, the direct current voltage having a same polarity as the discharge voltage.
