第１項または第２項記載の積層断熱構造。[Claims for Utility Model Registration] (1) Laminated heat insulation formed by alternately stacking metal-deposited plastic films such as aluminum and spacers with low thermal conductivity in the vacuum space between the inner container and the outer container. In the cryogenic laminated insulation material provided with a material layer, vapor-deposition-free slit portions are formed on one or both sides of the plastic film with appropriate gaps, and the slit portions are laminated so that the top and bottom do not overlap. A laminated insulation structure for extremely low temperatures that prevents the generation of eddy currents. (2) The laminated heat insulating structure according to claim 1, wherein the non-evaporated slit portions form a striped pattern or a lattice pattern. (3) In the case of metal vapor deposition on both the front and back surfaces of a plastic film, the laminated heat insulating structure according to claim 1 or 2, which is formed so that the undeposited slits do not overlap on the front and back surfaces.
