Abstract
A plate-type-ozonizer discharge cell including a pair of planar electrodes separated by a dielectric to ozonize a material gas circulating through a discharge space formed between one of the planar electrodes and the dielectric by way of discharge. In addition, the dielectric includes at least one ceramic block having a plurality of ceramic layers integrally superimposed on each other in a layer thickness direction. Also included is a method of manufacturing an ozonizer discharge cell, which includes providing a plurality of ceramic sheets to be baked, and superimposing the ceramic sheets in a layer thickness direction. Then the plurality of ceramic layers are baked so as to form a ceramic block.
