<p>A double-glazing unit comprising a pair of flat glasses (1), a plurality of spacers (2) provided between the flat glasses so that the spacers are spaced at intervals along the plate glass surfaces, a seal member (4) provided along the whole circumferential edge portion of the two flat glasses (1), and hollow portions (V) between the flat glasses (1) sealed in a vacuumed state, wherein the spacers (2) are formed so as to maintain a predetermined distance between the flat glasses against a normal static external pressure normally exerted in the direction of the glass thickness, and plastically deform and ease stress against an impact force exerted thereon dynamically in the direction of the glass thickness.</p> |
