Provided is a shoe cleaner which can be used by a user without exposing the user to high concentrations of ozone, and moreover is compact, is easy to use, and has low power consumption. The shoe cleaner is equipped with a case body and a sheet-like ozone generating body. The ozone generating body is formed from a flexible substrate and a flexible polymer resin electrode sheet. The electrode sheet is formed from a dielectric and electrodes covered by the dielectric. The case body houses a boost circuit for boosting the voltage of a battery and supplying the voltage to the electrode sheet.

A linear flexible plasma generator having a function of cooling and temperature control. More efficient power control is possible, since a temperature of an electrode itself can be controlled in a state when plasma is discharged. In addition, since a temperature of the electrode surface can be decreased, use for the purposes of sterilization, neutralization, treatment, beauty treatment, and so on is possible.
