Abstract: A low melting point tin phosphate-based glass frit contains, in mol %, 15-75% of SnO, 0-40% of SnF2, 10-50% of P2O5, 0-30% of ZnO, 0-5% of Al2O3, 0-30% of B2O3, 0-5% of In203, 0-5% of BaO, and 0-5% of SiO2, does not contain Pb, and exhibits a temperature difference of 50° C. or less between the glass transition point to the glass softening point. The glass frit has a low softening point temperature and a conventional glass transition point temperature without using a substance that places a burden on the environment such as lead.

Abstract: Provided is a super low melting SnO—SnF2—P2O5-based glass frit for which the firing temperature can be set to 200° C. or less and which has high water resistance and transparency. The fluorinated tin-based glass frit includes, in mol %, 30 to 70% of SnF2, 10 to 30% of P2O5, 10 to 40% of SnO, 0.1 to 10% of SnO2, 0 to 5% of In2O3, 0 to 5% of B2O3, and 0 to 5% of SiO2, and has a glass transition point of 160° C. or lower, a softening point of 180° C. or lower, and a maximum particle size of 100 ?m or less. The fluorinated tin-based glass frit has a visible light transmission rate of 80% or more at 200° C. and a thickness of 0.6 mm of a fired product thereof, and a rate of volume reduction of the fired product due to soaking in hot water at 85° C. for 24 hours is 2 vol. % or less.
