PROBLEM TO BE SOLVED: To provide a joint seal material capable of improving the building-up workability of exterior wall panels for a house and of enhancing waterproofness at reverse-T-shaped intersection or T-shaped intersection or the neighboring places. SOLUTION: This joint seal material is for providing watertightness at T-shaped or reverse-T-shaped intersections of vertical joints VJ and horizontal joints HJ created between opposite end faces of exterior wall panels OW for each house. Also, a vertical joint seal material VS comprising a vertical joint primary waterproof material VS1 and a vertical joint secondary waterproof material VS2, a horizontal joint seal material HS comprising a horizontal joint primary waterproof material HS1 and a horizontal joint secondary waterproof material HS2, and also a T-shaped intersection insert or a reversed T-shaped intersection insert RTJI which is inserted to a T-shaped or reversed-T-shaped intersection TJ or RTJ with the vertical joint secondary waterproof material VS2 and the vertical joint secondary waterproof material HS2 is provided. And then good waterproofness can be secured by the simple insertion of a T-shaped intersection insert or a reversed T-shaped intersection insert RTJI to the T-shaped or reversed-T-shaped intersection JS or RJT and its vicinities.
