PROBLEM TO BE SOLVED: To provide a multilayer structure having high heat insulation properties and transparency and excellent in security, safety and handleability. SOLUTION: The multilayer structure is composed of a structure in which three or more layers of base film 1 face with each other while sandwiching a plurality of resin spacers 2 in between, and resin spacers 2 are laid on top over another in the direction of the lamination of base films 1 while sandwiching a base film 1 in between. The lower limit of the whole light transmittance measured according to JIS K 7105 of a 2 mm-thick sheet formed of the resin composition for the spacer is 70%. The lower limit of the tensile strength measured according to JIS K 7127 of a 1 mm-thick sheet formed of the resin composition for the spacer is 0.5 MPa. COPYRIGHT: (C)2008,JPO&INPIT
