<p><P>PROBLEM TO BE SOLVED: To provide copper based electrode, electrode paste, an electronic component using it which are lower in cost than a silver electrode, and likewise the silver electrode, which can calcine in oxidation atmosphere such as atmosphere; and provide an electrode, electrode paste and an electronic component using it which can calcine at low temperature in an inactive gas atmosphere such as nitrogen. <P>SOLUTION: The present invention characterizes that it is an electrode at least comprised of metal particles and oxide phase. The metal particle contains copper and aluminum, and the oxide phase contains phosphorus. Preferably, the oxide phase exists in grain boundary of the metal particles as phosphate glass phase. Preferably, the metal particles are 75 to 95 vol.%, and the oxide phase is 5 to 25 vol.%. A preferable composition range of copper and aluminum in the metal particles is 80 wt.% or more and 3 wt.% or more in calcination of oxidized atmosphere, and 97 wt.% or more and 3 wt.% or less in calcination of inactive gas atmosphere. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
