<p>PURPOSE:To suppress characteristic deterioration even in a high humidity environment, in an ionic solution such as brine environment, and also in soldering by causing a reduced layer, formed by reducing a semiconductor porcelain surface, to have lower resistance as compared with a layer directly under the reduced layer. CONSTITUTION:Electrically conductive paste, whose main component is a metal powder of Ag, Cu, Ni, etc., is applied to a semiconductor porcelain surface, and this is baked in a reducing atmosphere or in a neutral atmosphere to form a reduced layer having resistance lower than that of a layer directly under this layer. A nonlinear resistor, whose main component is SrTiO3 for example, is used as the semiconductor porcelain, and the porcelain is obtained by baking it in a neutral atmosphere (N2) at 1480 deg.C and further in the air.</p> |
