Abstract: PROBLEM TO BE SOLVED: To reduce weight, and to enable connecting work such as nailing by laminating a vacuum heat insulating layer composed of a vacuum vessel and rigid panel layers connectably constituted by a connecting tool, by a heat insulating panel laminated with two or more layers. SOLUTION: A laminated heat insulating panel P applied to a refrigerator and a building material field is formed as a three-layer structure by sandwiching a vacuum heat insulating layer 1 by two rigid panel layers 2a, 2b. In this vacuum heat insulating layer 1, a small chamber division structure body 15 is loaded in a vacuum vessel 10 formed of a side plate by the opposed metallic plate parts 11, 12 and the left/right resin plate parts 13, 14.
