Recently, KH_2PO_4 (KDP) crystal is used to the high speed shutter or the modulator of Laser by a Kerr-effect of it. In these cases, as a leakage light of any incidence angle increases according to the thickness of the crystal plate, it is better to use the thinner plate. On the other hand, a transparent light is proportionately with the applied voltage for the crystal plate, so that, it is necessary to know the limitting voltage whose it can be possible to impress it, and the leakage current of it. Therefore, we study the temperature characteristics of a electric conductivity in the direction of each crystal axis with a silver paint and silver leaf electrodes, for the temperature between from 10℃ to 130℃. As the result, we know that it has the values of 10^<-10>℧/cm∿10^<-7>℧/cm, and increases exponentially according to the temperature, further, the electric conductivity of x-cut plate is larger than that of z-cut.
