PROBLEM TO BE SOLVED: To provide an ozonizer with an electrode structure where dismantling/cleaning is facilitated, and recycling is possible since, when discharge is repeated in an ozonizer, there is a risk that nitrogen oxide is stuck to the greater part of a dielectric substance by the excitation of oxygen atoms, thus a hole or the like is made in electrodes, and ozone starts to leak to cause the breakage of the whole apparatus. SOLUTION: In the ozonizer where an dielectric substance 4 is arranged between concentrically and cylindrically arranged electrodes 2, 3, either of the inner and outer electrodes is screwed with a front face connection part (front cover) 5 provided with a gaseous starting material introduction port 9 and a generated ozone gas discharge port 10, and the other is screwed with a back cover 6 so as to be freely removable, respectively. Further, a spacer 7 for holding the spacing between the concentrically and cylindrically arranged inner and outer electrodes 2, 3, at the inside of the back cover 6, thus the dismantling/cleaning of each part is facilitated.
