[Object] To provide a vanadium-based glass material used for sealing between glass substrates in a flat display by laser heating, the glass material being excellent in low-temperature workability and laser sealability, being capable of forming a sealing glass layer having a very low thermal expansion coefficient and extremely excellent water resistance, and being capable of reducing material costs greatly. [Solution] The vanadium-based glass material for local heat sealing has a glass composition containing, in terms of mol%, 30.0 to 60.0% V 2 O 5 , 20.1 to 30.0% ZnO, 10.0 to 25.0% TeO 2 , 1.0 to 5.0% Al 2 O 3 , 0.5 to 5.0% Nb 2 O 3 , 0 to 10.0% BaO, 0 to 5.0% Fe 2 O 3 , 0 to 5.0% MnO, 0 to 5.0% CuO, 0 to 5.0% SiO 2 , and 0 to 8.0% CaO, and substantially not containing Pb and P. |
