A vacuum insulated panel that is lightweight, thin and has excellent insulating properties. A tightly sealed space is formed by disposing a pair of side panels to face each other and disposing four frame pieces along the various sides of the side panels. Using an exhaust port, the tightly sealed space is evacuated. In the tightly sealed space, an inner panel of stainless steel, etc. is disposed to be substantially parallel to the side panels. Multiple protrusions are disposed on the inner panel. As a result of the protrusions contacting the inner surface of the side panel with the tips thereof, the side panels are supported. The protrusions are formed from a material with a lower thermal conductivity than the inner panel such as glass or ceramic. |
