Abstract
A glass containing no lead and comprising, calculated as oxides: 40-60 wt. % ZnO, 15-35 wt. % BO, 1-16 wt. % SiO, 1-10 wt. % AlO, 2-15 wt. % MnO, and at least one selected from the group consisting of LiO, NaO and KO 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 LiO, NaO and KO is 0-5 wt. %, and at least one selected from the group consisting of MgO, CaO, TiO, CrO, ZrO, TaO, SnO, and FeOis 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.
