<P>PROBLEM TO BE SOLVED: To prevent damage caused by a difference in a thermal expansion coefficient between a glass pane and a resin plate over a long period, in a state of hardly impairing transparency. <P>SOLUTION: In this double layer panel, mutual plate surfaces of a first plate material P1, a second plate material P2 and a third plate material P3, are mutually opposed at an interval in recording order; gas is sealed in a sealed space B formed by sealing a peripheral edge part between the first plate material and the second plate material, and between the second plate material and the third plate material; any one of a combination of the first plate material and the third plate material or the second plate material, is composed of the glass panes G1 and G2; and the other is composed of the resin plate 5. The double layer panel is constituted so that the second plate material is relatively displaceably supported in the direction along the plate surfaces to a seal layer, by holding the peripheral edge part of the second plate material on the inside of the seal layer over the whole periphery, by arranging the seal layer 6 capable of sealing the inside by adhering the mutual peripheral edge parts of the first plate material and the third plate material over the whole periphery. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
