PROBLEM TO BE SOLVED: To provide a heat-insulating air-tight exterior wall structure that allows air-tightness work to be performed on a seam part between a board-form heat insulation materials on an inner side of an exterior panel, from outside the exterior panel.SOLUTION: A heat-insulating air-tight exterior wall structure includes: two exterior panels positioned with an interval that forms a joint; two board-form heat insulation materials installed on an inner surface side of the two exterior panels, disposed to have a seam part between the board-form heat insulation materials positioned along a direction of extension of the joint, at a bottom of the joint; a fitting substrate material on which the exterior panels and the board-form heat insulation materials are fixed; and a gasket inserted into the joint from an outer surface side. An adhesive part is formed on an inner surface of the gasket, to adhere on both outer surfaces of the two board-form heat insulation materials at the seam part. |
