ABSTRACT:
A glass containing no lead and comprising, calculated as oxides: 40-60 wt. % ZnO, 15-35 wt. % B2O3, 1-16 wt. % SiO2, 1-10 wt. % Al2O3, 2-15 wt. % MnO2, and at least one selected from the group consisting of Li2O, Na2O and K2O in their total of 0.5-10 wt. %, and a glass with the above-described components where a total of at least one selected from the group consisting of Li2O, Na2O and K2O is 0-5 wt. %, and at least one selected from the group consisting of MgO, CaO, TiO2, Cr2O3, ZrO2, Ta2O5, SnO2, and Fe2O3is further included in their total of 0.1-5 wt. %. A conductive paste using such a glass as an inorganic binder has a superior binder removal ability and a good sinterability and can form dense conductors with excellent characteristics with respect to resistance to plating solutions, adhesive strength, resistance to thermal shocks, etc.
