To develop a vanadium-based glass composition that has excellent low-temperature sealing properties and fluidity, and obtains a vanadium-based material that is less susceptible to airtight defects such as leaks due to mechanical impacts. 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 1 to 20 in terms of mass% based on the following oxides. %, BaO 5 to 35%, SrO 1 to 15%, CaO 0 to 5%.
