A glass panel (P) comprising a pair of sheets of plate glass (1A, 1B) with their plate surfaces opposed to each other, a distance-holding spacer (2) interposed therebetween, a sealing material (3) whose melting point is lower than that of the plate glass and which is used to seal the spacing between t he outer peripheral edges (9) of the pair of sheets of plate glass (1A, 1B) so that a pressure reduction gap (V) is defined between the pair of sheets of plate glass (1A, 1B), wherein with the pressure reduction gap (V) in a norma l pressure state, a compressive force (Fc) is allowed to remain on the outer surface side peripheral edge (9) of the plate glass (1) or the cutter-cut ed ge of the plate glass is arranged to face the pressure reduction gap or the atmosphere side edge of the plate glass is chamfered by grinding, whereby wi th the pressure reduction gap in a reduced pressure state, the plate glass is prevented from cracking owing to a flaw in the surface of the plate glass or owing to an external force acting on the plate glass.
