<p>PURPOSE:To obtain a voltage-dependent nonlinear resistance element having an excellent characteristic by a method wherein a paste composed mainly of Cu is dried in the air and an ohmic electrode is formed on a sintered substance composed mainly of SrTiO3. CONSTITUTION:A paste whose main component is Cu and which contains a borosilicate lead-based glass frit and a resin is applied, by using a screen printing method, to a region used to form electrodes of a sintered substance 1 composed mainly of SrTiO3. Then, this paste is dried in the air, a resistance element having ohmic electrodes 2a-2c composed mainly of Cu is obtained on the sintered substance 1. By this setup, the electrodes come into ohmic contact with the sintered substance, and an interface between the sintered substance and the electrodes has not rectification action; accordingly, voltage nonlinearity of the sintered substance itself can be displayed sufficiently.</p> |
