Abstract
A dust-collecting electrode where at least one unit electrode between the unit electrodes facing each other includes: a ceramic dielectric body, a surface conductor disposed so as to cover at least a part of the surface of the ceramic dielectric body on the side where the unit electrodes face each other, and an internal conductive layer disposed inside the ceramic dielectric body and being electrically independent of the surface conductor. The dust-collecting electrode being capable of generating an electric field and silent discharge between the unit electrodes by applying voltage between the surface conductor of the one unit electrode and the other unit electrode and generating creeping discharge on the surface of the one unit electrode by applying voltage via the ceramic dielectric body.
