摘要

Disclosed is a lead-free glass, which is characterized by comprising 5-55 weight % of V 2 O 5 , 5-75 weight % of TeO 2 , 6-20 weight % of a total of RO (at least one selected from the group consisting of MgO, CaO, SrO and BaO) and 0.1-6 weight % of ZnO in a glass component, V 2 O 5 + TeO 2 + RO + ZnO being 70 weight % or greater. From this lead-free glass, a sealing material having fluidity which is capable of sealing at 400°C or lower can be obtained.
