An ion generating element (10) has at least one first discharge portion (12) for generating positive ions and at least one second discharge portion (13) for generating negative ions. The first and second discharge portion (12, 13) are mounted or printed on one dielectric body (11). The first discharge portion (12) has a pair of a first discharge electrode (12a) and a first induction electrode (12b). The second discharge portion (13) has a pair of a second discharge electrode (13a) and a second induction electrode (13b). The first and second discharge electrodes (12a, 13a) are provided on the surface of the dielectric body, and the first and second induction electrodes (12b, 13b) are buried in the dielectric body (11). The first and second discharge portions (12, 13) are spaced from each other independently on the same plane of the dielectric body (11). With this structure, neutralization of generated ions is suppressed and positive and negative ions can be emitted effectively, thereby further improving the ion generation efficiency. |
