PROBLEM TO BE SOLVED: To obtain a maintenance-free ion generator in which electrodes are not heated to a high temperature; dry air is not required for the air as the raw material for ozone; nitric acid is not generated by the moisture and NOx in the air; the corrosion of the electrodes and consequent failure in ozone generation do not occur; and the cleaning and exchanging of the electrode sections are not required at the time of continued use. SOLUTION: The ozone generator shuts off the electrodes from the air, wherein double cylindrical dielectric substances are composed of the dielectric substance A of an inner side and the dielectric substance B of an outer side; the electrode A of stainless steel foil etc., is stuck to the inner side of the dielectric substance A and the electrode B of stainless steel foil etc., is stuck to the outer side of the dielectric substance B to cover the outer periphery of the electrode B so as to prevent contact of the air therewith; a holder 1 and a holder 2 shut off the air on the side face of the dielectric substance A; a discharge space is provided between the outer side of the dielectric substance A and the inner side of the dielectric substance B; an air introducing port provided at the holder 1 and an ozone emission port provided at the holder 2 are communicated with the discharge space; and a high voltage power source is applied to the electrodes.
