To provide a vacuum heat insulating tile for construction formed into a tile shape capable of keeping high heat insulation performance by preventing intrusion of air in a vacuum heat insulating panel, and improving work efficiency.
On each of the upper surface and the lower surface of a rectangular flat vacuum heat insulating panel with a core material formed of a glass fiber 4 vacuum-sealed in a bag 3 formed of an air-non-permeable film, a protective plate 6 for protecting the air-non-permeable film of the bag 3 is stuck by an adhesive. Small openings formed around side surfaces by the sticking of the upper and lower protective plates 6 are filled with a seal material 7 to berry welding sheet parts 5. The upper and lower protective plates 6 are integrated with each other to form into a sealed tile shape, to thereby compose the vacuum heat insulating tile to be stuck to an architectural structure with an adhesive.
