    摘要： An object of the present invention is to provide an electronic component using a Cu-based conductive material that can suppress oxidization even in a heat treatment in an oxidizing atmosphere and that can suppress an increase in an electrical resistance. In an electronic component having an electrode or a wiring, a ternary alloy made from three elements consisting of Cu, Al, and Co is used as a Cu-based wiring material that can prevent oxidization of the electrode or the wiring. Specifically, part or the whole of the electrode or the wiring has a chemical composition in which an Al content is 10 at % to 25 at %, a Co content is 5 at % to 20 at %, and the balance is composed of Cu and unavoidable impurities, and the chemical composition represents a ternary alloy in which two phases of a Cu solid solution formed by Al and Co being dissolved into Cu and a CoAl intermetallic compound coexist together.
