Research Abstract	The relationships between the kind of the electrolyte and the current distribution from the local discharge on the electrode-fall of the local discharge were examined by using a variety of kinds of electrolytes. Moreover, the mechanism of maintenance of the local discharge was examined. As a result, it was found that the current distribution depended on the kind of the electrolyte and the electrode-fall increased with the resistivity of the electrolyte solution. Moreover, the light according to the electrolyte such as potassium and sodium were observed. Therefore, it has been thought that the local discharge has characteristics both of glow discharge and an arc discharge.
