To provide glass bonding material which can be preferably used for bonding for example, even a metal member which has a high thermal expansion coefficient and is suitably used even when bonded in a low temperature range (for example, about 600°C or less).SOLUTION: When setting the entire glass bonding material to be 100 mol%, 95 mol% or more of the glass bonding material includes, at a molar ratio in terms of oxide, the following composition: ZnO:1-5 mol%, Bi2 O3:0.1-5 mol%, Al2 O3:0.1-3 mol%, SiO2:40-55 mol%, TiO2:5-15 mol%, V2O5:1-5 mol%, P2O5:0.1-1 mol%, M2 O:25-40 mol% and M'O:0.2-3 mol%, (where, M is a first group element and includes 5 mol% or more of at least Li, Na and K at a molar ratio in terms of oxide, and M' is a second group element and includes 0.1 mol% or more of at least Mg and Ca at a molar ratio in terms of oxide, respectively.).SELECTED DRAWING: None
【課題】例えば熱膨張係数が高く、かつ、低温域下（例えば６００℃以下程度）での接合が好ましいとされる金属部材の接合においても好適に用いられ得るガラス接合材を提供する。【解決手段】ここで開示されるガラス接合材は、該ガラス接合材全体を１００モル％としたとき、９５モル％以上が酸化物換算のモル比で以下の組成：ＺｎＯ：１～５モル％、Ｂｉ２Ｏ３：０．１～５モル％、Ａｌ２Ｏ３：０．１～３モル％、ＳｉＯ２：４０～５５モル％、ＴｉＯ２：５～１５モル％、Ｖ２Ｏ５：１～５モル％、Ｐ２Ｏ５：０．１～１モル％、Ｍ２Ｏ：２５～４０モル％、Ｍ’Ｏ：０．２～３モル％（ここで、Ｍは第１族元素であり、少なくともＬｉ、Ｎａ、Ｋを酸化物換算のモル比でそれぞれ５モル％以上含む。また、Ｍ’は第２族元素であり、少なくともＭｇ、Ｃａを酸化物換算のモル比でそれぞれ０．１モル％以上含む。）を含んでいる。【選択図】なし
