Conductive paste, outer electrode and process for producing the same

Abstract

The present invention provides a conductive paste for an outer electrode of an electronic part comprising glass frit, a vehicle and conductive particles, wherein the glass frit comprises (1) substantially no lead oxide; and (2) as an oxide unit, B2O3 in an amount of 5.0 to 30.0% by weight, SiO2 in an amount of 10.0 to 60.0% by weight and at least one oxides selected from the group consisting of BaO, ZnO, Al2O3 and Na2O wherein a content of BaO is 60.0% by weight or less, a content of ZnO is 30.0% by weight or less, a content of Al2O3 is 12.0% by weight or less and a content of Na2O is 15.0% by weight or less; an outer electrode of an electronic part obtained by calcining the conductive paste; and a process for producing an outer electrode which comprises the step of calcining the conductive paste at a temperature of 500 to 750° C.
