a first electrode disposed on a first surface of the dielectric substrate;

a second electrode disposed on the dielectric substrate and corresponding to the first electrode; and

wherein the first electrode comprises a plurality of first finger portions and a plurality of superficial structures integrally formed on the plurality of first finger portions; and

wherein the first electrode has a flat surface at a side of the first electrode located opposite to the dielectric substrate, and the plurality of superficial structures are disposed only on side surfaces of the first electrode.

2 . The ozone generator according to claim 1 , wherein the second electrode is disposed on the first surface of the dielectric substrate.

3 . The ozone generator according to claim 2 , wherein the second electrode includes a plurality of second finger portions, and the plurality of first finger portions and the plurality of second finger portions are alternately arranged.

4 . The ozone generator according to claim 1 , further comprising a conductive layer disposed on a second surface opposite to the first surface and served as a ground layer.

5 . The ozone generator according to claim 1 , wherein the dielectric substrate has a second surface opposite to the first surface, and the second electrode is disposed on the second surface.

6 . The ozone generator according to claim 5 , further comprising a chamber body fixed to the second electrode, wherein the chamber body and the second electrode together enclose the dielectric substrate and the first electrode therein.

7 . The ozone generator according to claim 6 , wherein the plurality of first finger portions are located between a gas inlet and a gas outlet of the chamber body.

8 . The ozone generator according to claim 5 , wherein the second electrode comprises a plurality of fin structures extending outwards from a surface of the second electrode opposite to the first electrode.

9 . The ozone generator according to claim 1 , wherein each of the plurality of superficial structures is a thread.

10 . The ozone generator according to claim 9 , wherein the plurality of superficial structures have a thread pitch ranging between 1.2 millimeters and 3.7 millimeters.
