Recently, ozone has been utilized in various fields thanks to its effectiveness, and has been in ever-growing demand. Accordingly, various kinds of ozonizers have been examined among researchers. This paper is concerned with developing the cascade-type plate electrode ozonizer(PTO) for improvements of indoor air, water supply and drainage and investigating its characteristics. Four types of ozonizers have been devised according to their size, numbers and arrangement Electric discharge area of each type of ozonizer has the same size of 22,400[$mm^2$], and its discharge power has the maximum 40[w]. As the result of having studied ozone generation ozone concentration and ozone yield characteristics of each ozonizer, we found that the type of ozonizer in which eight plates were arranged into cascade type(PTO-4) was the most excellent one.
