Abstract

An ozone generation device has a cylindrical first electrode a cylindrical second electrode disposed on the same axis as the first electrode and within the first electrode and a dielectric body disposed between the first electrode and the second electrode. In the ozone generation device dry air is supplied as the starting material gas between the first electrode and the second electrode a discharge is generated as a consequence of a high voltage being applied between the first electrode and the second electrode and ozone is generated by means of said discharge. The discharge gap length (d) formed by means of the first electrode and the second electrode and the dielectric body is between 0.3 and 0.5 mm. The product (pd) of the discharge gap length (d) and the gas pressure (p) of the starting material gas is between 6 and 16 k Pa-cm. Moreover the discharge gap length (d) and the gas pressure (p) of the starting material gas are set so as to satisfy the following equation: (pd-250d-3.16) 2+150d=12.5.
