The present invention is a conductive paste comprising a conductive powder, a glass frit, and an organic vehicle, wherein the conductive powder comprises copper and/or nickel as a main component(s), and the glass frit is substantially free of Pb, Cd, and Bi, comprises 40 to 65% by mass of BaO, 15 to 23% by mass of B 2 O 3 , 2 to 12% by mass of Al 2 O 3 , 4 to 8% by mass of SiO 2 , 0 to 5% by mass of ZnO, 0.5 to 7% by mass of TiO 2 , 3 to 7.5% by mass of CaO, and comprises any one or more of MnO 2 , CuO, and CoO in the ranges of 0 to 7% by mass of MnO 2 , 0 to 16% by mass of CuO, and 0 to 5% by mass of CoO, in terms of oxide.
According to the present invention, it is possible to provide a conductive paste that can form a dense electrode film that has excellent acid resistance and is free from insufficient strength and infiltration of a plating solution, even in the case of firing in a non-oxidizing atmosphere.
