Shoe cleaner

Abstract

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.
