Abstract
The invention is a conductor paste composition comprising a conductive material that contains silver as the essential component, and an inorganic binder as dispersed in a vehicle, wherein said inorganic binder contains, in terms of oxides, from 10 to 60% by weight of lead oxide (PbO), from 5 to 15% by weight of boron oxide (B.sub.2 O.sub.3), from 2 to 15% by weight of silicon oxide (SiO.sub.2), from 0.1 to 15% by weight of manganese oxide (MnO), and from 0.1 to 80% by weight of vanadium oxide (V.sub.2 O.sub.5). The invention realizes a conductor paste for outer electrodes having excellent mountability, high reliability in mounting and excellent electric properties for inner electrode co-fired, non reciprocal devices, and also realizes non reciprocal devices comprising it.
