A laminate, comprising
- at least one glass sheet and at least one resin layer,
- a relative dielectric constant of the glass sheet at 25° C. and a frequency of 2.45 GHz being 5 or less, and a dielectric loss tangent of the glass sheet at 25° C. and a frequency of 2.45 GHz being 0.003 or less,
- wherein the glass sheet comprises at least 60 mol % of SiO2, from 1 to 15 mol % of Al2O3, from 20 to 30 mol % of B2O3, from 0 to 6.2 mol % of MgO+CaO+SrO+BaO, from 0 to 5 mol % of MgO, and from 0 to 5 mol % of CaO in a glass composition.
