An ion generating apparatus is built by sandwiching a dielectric layer between an induction electrode and a discharge electrode. The induction electrode is formed of a metal substrate of, for example, aluminum. Even when the apparatus is made larger, it offers improved mechanical strength compared with a conventional structure employing a dielectric layer formed of a ceramic substrate, a brittle material. The dielectric layer is formed of a thin film having an insulation breakdown withstand voltage of 30 V/μm or more and having a thickness of 30 μm or less. The discharge electrode is formed on the dielectric layer such that the area occupied by the electrode portion of individual line-shaped electrodes is smaller than the area occupied by the non-electrode portion thereof. This helps to make the discharge voltage lower and to reduce the amount of ozone generated by electric discharge.
An ion generating apparatus that includes a dielectric layer sandwiched between an induction electrode and a discharge electrode and that generates both positive and negative ions by applying an alternating voltage between the induction electrode and the discharge electrode to cause electric discharge,
An air conditioning apparatus including:
A charging apparatus including:
