Abstract
Provided is a board for ion generation that is capable of generating negative ions with much better efficiency and in an amount larger than that of positive ions. In the board for ion generation, a discharge electrode is formed on one principal surface of a substrate formed of ceramics, an induction electrode is formed on another principal surface of the substrate, the discharge electrode and the induction electrode being disposed opposite to each other, a first protective layer and a second protective layer are formed so as to cover the discharge electrode and the induction electrode, respectively. Surface discharge is generated on a surface of the first protective layer by applying an AC voltage between the discharge electrode and induction electrode, and positive ions and negative ions are alternately generated in the air. In the board for ion generation, the porosity of the substrate is 5 to 10 vol. %.
