  • ION GENERATION UNIT
    Publication number: 20140225001
    Abstract: An ion generation unit (1) provided with an ion generation element (20) for generating ions through application of voltage, and a casing (10) housing the ion generation element. The casing is constituted by a casing body (11) and a rear cover (12). To the inside face of the casing are attached suppressing members (30, 31, 32, 33) for suppressing the radiation noise associated with ion generation. Openings (13, 14) through which the ions generated by the ion generation element are emitted to the outside are formed in the casing body, and the suppressing members are attached at locations other than the openings.
