<p>PURPOSE:To provide a voltage nonlinear resistance element with such an inexpensive ohmic electrode that the electrode has excellent solder wettability and a strong strength of adhesion and stable electrical characteristics can be obtained without forming any potential barrier. CONSTITUTION:An ohmic electrode to be formed on the surface of a semiconductor ceramic in a coating state is composed of silver containing glass frit and at least one kind selected out of metallic tin and stannous oxide and the mixing amounts of the glass frit and metallic thin or stannous oxide against 100 pts. silver are respectively set at 1.5-6.0 pts. and 0.5-10.0 pts.</p> |
