Abstract

An AgO—VO—TeOlead-free low-melting glass composition that is prevented or restrained from crystallization by heating so as to soften and flow more satisfactorily at a low temperature contains a principal component which includes a vanadium oxide, a tellurium oxide and a silver oxide; a secondary component which includes at least one selected from the group consisting of BaO, WOand PO; and an additional component which includes at least one selected from the group consisting of oxides of elements in Group 13 of periodic table. A total component of the principal component is 85 mole percent or more in terms of VO, TOand AgO. Contents of TeOand AgO each is 1 to 2 times as much as a content of VO. A content of the secondary component is 0 to 13 mole percent. A content of the additional component is 0.1 to 3.0 mole percent.
