<p>A light-transmitting glass panel having high thermal insulation performance with thermal conductance sufficiently reduced. The light-transmitting glass panel 1 is comprised of a pair of glass plates 11 and 12 that are hermetically joined together with one surface of each thereof facing one another, the joining being via a sealing frame 13 that is provided at an outer peripheral portion of the glass plates 11 and 12 and fluidizes at low temperature, and the glass plates 11 and 12 having a hollow layer 14 formed therebetween, and pillars 15 that are substantially cylindrical spacers that are inserted into the hollow layer 14 as atmospheric pressure supporting members and determine the gap between the glass plate 11 and the glass plate 12. The pillars 15 are arranged in the hollow layer 14 in a matrix shape with a predetermined spacing, and taking the surface residual compressive strength of the glass plates 11 and 12 in MPa to be S, and the thickness of the glass plates 11 and 12 in mm to be d, the average spacing D in mm of the pillars 15 arranged in the hollow layer 14 satisfies the relationship D≤5.2d + 5.5 + (0.8d + 0.08). 2ROOT S. <IMAGE></p> |
