PROBLEM TO BE SOLVED: To create a vanadium-based glass composition excellent in weatherability such as water resistance as well as in low-temperature sealing property, and to obtain a vanadium-based material maintaining airtightness over a long period of time. SOLUTION: The vanadium-based glass composition includes, indicated by mass% on an oxide basis, 30-60% V<SB>2</SB>O<SB>5</SB>, 15-40% P<SB>2</SB>O<SB>5</SB>, 0.1-15% ZnO, 0.1-10% CuO and 0-40% BaO as a glass composition.
