PROBLEM TO BE SOLVED: To improve bonding properties between a vacuum heat-insulating panel and inner surfaces of heat-insulating walls in a vacuum heat-insulating panel having adsorbent inside and improve the strength of the heat-insulating walls and further the whole of a heat-insulating box.SOLUTION: A refrigerator includes a heat-insulating box which is formed into a box shape by heat-insulating walls having heat-insulating properties and has a storage chamber inside. The heat-insulating walls are structured each by setting a vacuum heat-insulating panel between an inner plate and an outer plate. Adsorbent adsorbing gas is provided inside the vacuum heat-insulating panel. The vacuum heat-insulating panel is bonded to at least one of the inner plate and the outer plate. An opening part being at a position overlapping on the adsorbent and passing through the inner plate or the outer plate, is formed on the inner plate or the outer plate to which the vacuum heat-insulating panel is bonded. |
