description PROBLEM TO BE SOLVED: To provide an ozone generating apparatus having good ozone generation (power) efficiency, and more specifically to provide an ozone generating apparatus which can reduce the amount of cooling water and is simple in the construction of the power source, and in which a stable operation is possible. SOLUTION: In an ozone generating apparatus which has a plasma generation part provided with a pair of opposing electrodes 2, 2' and solid dielectric layers 3, 3' that are arranged on the opposing surface of at least one of the electrodes of the pair of electrodes 2, 2', and which generates ozone from a raw material gas 6 by supplying the raw material gas 6 that contains oxygen into the space 10 between the pair of electrodes 2, 2', and by using discharge generated by impressing pulsed voltage between the pair of electrodes 2, 2', the ozone generating apparatus uses a gap between the pair of electrodes 2, 2' of not larger than 0.4 mm, a pulse duration of the pulsed voltage of not longer than 10 μsec, and a value of input power/gas flow volume of at least 30 W×min/NL.
