PROBLEM TO BE SOLVED: To provide a multiple wall structure which prevents flexure or cracks of a transparent multiple wall caused by a change of stress accompanied by a thermal expansion of a wall body, prevents condensation on a transparent wall surface or on the transparent wall surface on a gap part side, and prevents reduction of the transparent wall surface. SOLUTION: In the multiple wall structure, each of a plurality of transparent wall bodies is placed in a state that its wall surface faces the other transparent wall body adjacent thereto. The transparent wall body and the other transparent wall body adjacent to and facing each other are connected by a deformable connector by the intermediary of the gap part. Further, part of or whole of the gap part is sealed. COPYRIGHT: (C)2004,JPO&NCIPI
