PROBLEM TO BE SOLVED: To provide a repair structure which prevents a waste material etc. from being produced in a building exterior wall, constituted by providing a vent layer between a heat insulating material layer and an external facing material arranged outside the heat insulating material layer, and which enhances the heat insulation performance of the exterior wall of the building by easy construction. SOLUTION: In the exterior wall 1 of the building, a first external facing material layer 25 is arranged on the outside of a first heat insulating material layer 22; and the vent layer 26 is formed between them. When the exterior wall 1 is repaired, a new second heat insulating material layer 33 is arranged outside the first external facing material layer 25; and a new second external facing material layer 34 is arranged outside the second heat insulating material layer 33. Preferably, a ventilation suppressing material 31 suppressing the inflow of outside air is arranged at the peripheral edge of the vent layer 26. COPYRIGHT: (C)2011,JPO&INPIT
