Abstract
An ionizer includes a fan for blowing air, the fan being provided in an air blowing port which opens in a case, and a plurality of discharge electrodes for generating positive and negative ions by corona discharge, the discharge electrodes being provided in the case at positions facing the air blowing port. The ionizer also includes a plurality of discharge electrode pairs each constituted by two discharge electrodes for generating ions of different polarities. When a tip-center distance denotes a distance from the electrode tip to the center of the air blowing port, the tip-center distances of the two discharge electrodes in the discharge electrode pairs are different from each other.
