Abstract: An ion generating element includes a positive ion discharger for generating positive ions and a negative ion discharger for generating negative ions. The ion dischargers are arranged separately from and independently of each other with a distance securing insulation between them. At least one of the dischargers includes a discharging portion for causing electric discharge, and a conducting portion having a voltage same as the discharging portion. The conducting portion surrounds a perimeter or part of the discharging portion. The conducting portion may surround a perimeter or part of the discharging portion so as to partition the ion dischargers from each other.

Abstract: An ion generating apparatus includes an ion generating element having a positive ion discharger for generating positive ions, and a negative ion discharger for generating negative ions. The positive ion discharger and the negative ion discharger are arranged separately from and independently of each other on a base member with a distance securing insulation between the positive and negative dischargers. The ion generating apparatus also includes a blower for releasing the ions generated by the positive and negative ion dischargers into air and a voltage application circuit. The blower blows wind in a direction parallel to a surface of the base member.

Abstract: An ion generating element (10) has at least one first discharger (12) for generating positive ions and at least one second discharger (13) for generating negative ions, both fitted or printed on a single dielectric member (11). The first and second dischargers (12) and (13) are each composed of a pair of a first or second discharging electrode (12a) or (13a), respectively, formed on the surface of the dielectric member (11) and a first or second induction electrode (12b) or (13b), respectively, buried in the dielectric member (11), and are arranged both on the same flat surface of the dielectric member (11) but separately from and independently of each other. This construction helps to alleviate the neutralization among the generated ions themselves, thus to effectively release both positive and negative ions, and thereby to enhance the ion generation efficiency.
