Abstract: A discharge cell for use in an ozone generator includes first upper and lower electrodes (10) formed of flat rigid bodies, which are opposed with a pair of rigid spacers (20) placed between them to define a space. This space accommodates a dielectric unit having a rigid structure including a second electrode (32) sandwiched between two glass plates (31,31). A plurality of spacers (40,40,...) are inserted between the dielectric unit (30) and the first electrodes (10) so that the dielectric unit (30) can be held at a neutral position in the space to form a discharge gap (50) on each side. The discharge gap G can remain to be as narrow as less than 0.4 mm. The cell components and fastening mechanism are protected from damage.
