The object of the present invention is to develop a vanadium-based glass composition that has excellent low-temperature sealing properties and excellent weather resistance such as water resistance, and obtains a vanadium-based material that can maintain hermeticity for a long period of time. The vanadium-based glass composition of the present invention has, as a glass composition, V 2 O 5 30 to 60%, P 2 O 5 15 to 40%, ZnO 0.1 in terms of mass% based on the following oxides. It is characterized by containing -15%, CuO 0.1-10%, BaO 0-40%. [Selection figure] None |
