GLASS UNIT
A glass unit according to the present invention includes a first glass plate, a second glass plate that is arranged facing the first glass plate with a predetermined interval therebetween and forms an internal space with the first glass plate, a sealing member that seals a gap at peripheral edges of the first glass plate and the second glass plate, and a plurality of spacers arranged between the first glass plate and the second glass plate. The internal space has been depressurized to a vacuum state, the first and second glass plates each have a thickness of 5.0 mm or less, and expressions (1) and (2) below are satisfied for a cross-sectional area S (mm2) of the spacers: (1) R≤(800/π)*S+13, and (2) 25*10-4π≤S≤400*10-4π, where R is the distance to a spacer closest to a certain spacer.
