Abstract
An ion generating apparatus has: a housing having an intake port and an exhaust port; a fan having an impeller and a casing accommodating the impeller, and accommodated in the housing; a filter passing the air taken in through the intake port by the fan; and two ion generating parts generating positive ions and negative ions. The ion generating parts are arranged in an arc-shaped guide wall of the casing. The positive ions and the negative ions generated by the ion generating parts are efficiently mixed into air flowing in a state of laminar flow along the arc-shaped guide wall.
