Abstract
It is an objective of the invention to provide a conductive joint article exhibiting electrical joinability comparable to that of solder joining of easy-to-solder joinable metals even when a joined member of the conductive joint article is made of a hard-to-solder joinable metal. There is provided a conductive joint article with conductive joined members electrically joined via a joining layer, at least one of the joined members being made of a hard-to-solder joinable metal. The joining layer comprises an oxide glass phase and a conductive metal phase. The oxide glass phase includes vanadium as a major constituent and at least one of phosphorus, barium and tungsten as an accessory constituent, and has a glass transition point of 390° C. or less. And, connection resistance between the joined members exhibits less than 1×10−5 Ω/mm2.
