Abstract
Disclosed is an AgO—VO—TeOlead-free low-melting glass composition that is prevented or restrained from crystallization so as to soften and flow more satisfactorily at a low temperature. This lead-free low-melting glass composition contains a principal component; and an additional component. The principal component includes a vanadium oxide, a tellurium oxide and a silver oxide. The additional component includes at least one selected from the group consisting of yttrium oxide and lanthanoid oxides. A content of the additional component is 0.1 to 3.0 mole percent in terms of oxide. The additional component preferably contains at least one selected from YO, LaO, CeO, ErO, and YbOin a content of 0.1 to 2.0 mole percent in terms of oxide. The additional component particularly effectively contains at least one of YOand LaOin a total content of 0.1 to 1.0 mole percent.
