Claim:
A glass panel comprising: a pair of glass plates, each glass plate having a thickness of 3 mm to 4 mm and having plate surfaces opposed to each other; a number of space-maintaining members arranged between said pair of glass plates with predetermined intervals between rows along the plate surfaces; and a seal member having a melting point lower than the glass plates for hermetically sealing between said pair of glass plates at outer peripheral edges to form a void in a decompressed condition; and wherein an internal stress produced in a vicinity of outermost rows of said space-maintaining members positioned closest to the edges of said pair of glass plates is greater than an internal stress produced in a vicinity of the outer peripheral edges of said pair of glass plates, and wherein a dimension between the outermost rows of the space-maintaining members and the outer peripheral edges of said pair glass plates is set to at most 5.8 times a thickness of said pair of glass plates when the thickness is the same between said pair of plates or set to at most 5.8 times a thickness of a thinner glass plate when the thickness is different between said pair of glass plates.
