A heat-insulating box (1) according to the present invention includes: an outer casing (2); an inner casing (3) accommodated in the outer casing, such that heat insulating space is formed between the inner casing and an inner surface of the outer casing; a plurality of vacuum insulation panels (10) arranged in the heat insulating space; and a foam insulating material (4) which fills space in the heat insulating space other than the plurality of vacuum insulation panels. Each of the plurality of vacuum insulation panels includes at least a core material and a moisture adsorbent, and the core material and the moisture adsorbent are decompression-sealed in space covered by an outer skin material. Among the plurality of vacuum insulation panels, at least a vacuum insulation panel having a largest area includes a gas adsorbing device in addition to the core material and the moisture adsorbent, the gas adsorbing device having nitrogen adsorbing capability and moisture adsorbing capability, and the core material, the moisture adsorbent, and the gas adsorbing device are decompression-sealed in the space covered by the outer skin material. |
