ABSTRACT:
A glass containing 5 to 25 mass % of P2O5, 0 to 15 mass % of B2O3, 0 to 5 mass % of SiO2+GeO2, 21 to 50 mass % of BaO+SrO, 0 to 3 mass % of Li2O+Na2O+K2O, and 35 to 65 mass % of Nb2O5, not substantially containing PbO, satisfying Nb2O5/(BaO+SrO)=0.85 to 2.20, having a dielectric constant of 15 or greater, a dielectric loss of 10.0×10−4or less, and a resistivity of 1.0×1016Ω·cm or more.
