Abstract

An ionization device with increased rigidity of a coupling portion is provided. The ionization device includes a casing member for applying high voltage to each needle electrode; a coupling member for mechanically coupling a plurality of casing members in a longitudinal direction and electrically connecting high voltage plates of the respective casing members; and a elongated main body casing for housing a casing body constituted by coupling the plurality of casing members with the coupling member and the electrical circuit unit, the main body casing having the needle electrodes with a space from each other in the longitudinal direction and protruding outside. The main body casing integrally forms a space for arranging the casing body therein so as to be separated from a space for arranging the electrical circuit unit. With this configuration, the casing body to be applied with the high voltage is separated from the electrical circuit unit including a portion having low voltage, thereby avoiding unnecessary discharge.
