Abstract:
The conductive paste contains the following dispersed in a binder resin dissolved in a solvent: a plurality of particles comprising aluminum and/or an aluminum-containing alloy; and an oxide-comprising powder. The oxide contains vanadium with a valence no greater than 4 and a glass phase. In the method for manufacturing an electronic component, the conductive paste is applied to a substrate and fired, forming electrode wiring. The electronic component is provided with electrode wiring that has: a plurality of particles comprising aluminum and/or an aluminum-containing alloy; and an oxide affixing the particles to a substrate. The oxide contains vanadium with a valence no greater than 4. A compound layer containing vanadium and aluminum is formed on the surfaces of the particles, and the vanadium in the compound layer includes vanadium with a valence no greater than 4. This results in an electrode wiring with high reliability and water resistance.
