Abstract
A glass plate has a dielectric dissipation factor at 10 GHz of tan δA and a glass transition temperature of Tg° C. The glass plate satisfies (tan δ100−tan δA)≥0.0004, where tan δ100 is a dielectric dissipation factor of the glass plate at 10 GHz after having been heated to (Tg+50)° C. and then cooled to (Tg−150)° C. at 100° C./min.
