The present invention relates to a glass including, in mol % in terms of oxides: 68% or more of SiO2; 0.1% to 8% of Al2O3; and 0.1% to 4% of SrO, in which [SiO2]+[B2O3] is 88% or more, [B2O3]−([RO]+[R2O]−[Al2O3]) is 27% or less, a relative dielectric constant at 25° C. and a frequency of 10 GHz is 4.5 or less, a dielectric loss tangent at 25° C. and a frequency of 10 GHz is 0.005 or less, ΔAbs-OH is 4.0 or less, a total content (RO) of MgO, CaO, SrO, and BaO is more than 0% to 6%, a total content (R2O) of Li2O, Na2O, and K2O is 0% to 1%, [Al2O3]−[RO] is −3% to less than 8%, [Al2O3]×[RO] is more than 0 to 30, [MgO]+[CaO] is 0.1% to 5.9%, and [MgO]/([MgO]+[Al2O3]) is 0 to 0.45.
