Abstract: A glass material of a glass spacer has a surface resistivity of 103 to 109 [Ω/sq] at 22 [° C.]. The surface resistivity of a surface of the glass material of the glass spacer at 22 [° C.] is lower than the surface resistivity of an inner portion of the glass material at 22 [° C.]. The glass spacer contains at least one oxide selected from the group consisting of TiO2, Nb2O5, WO3, and Bi2O3, as a glass component.
