A glass composition being substantially free from lead and bismuth and containing phosphor oxide and up to 45% by weight of V2O5 as main components and manganese oxide and barium oxide, wherein a sintered glass obtained by sintering the glass composition exhibits a resistivity of 109 Ωcm or more at 25° C.
A glass composition being substantially free from lead and bismuth, wherein a sintered glass obtained by sintering the glass composition exhibits a resistivity of 10 Ωcm or more at 25° C., which comprises, based on conversions of oxides, 33 to 45% by weight of V2O5, 22 to 30% by weight of P2O5, 5 to 15% by weight of MnO, 10 to 20% by weight of BaO, 0 to 8% by weight of R20 where R is alkali metals, and 0 to 10% by weight in a total amount of at least one of Sb2O3, TeO2, ZnO, SiO2, Al2O3, Nb2O5 and La2O3.
