摘要

PROBLEM TO BE SOLVED: To provide an airtight structure between an exterior wall and a ceiling capable of improving airtightness between the exterior wall and the ceiling and realizing a highly airtight house. SOLUTION: A flexible airtight sheet 5 is integrally stretched from the upper end of an inside face member 2 provided at the indoor side face of an exterior wall panel 1 perpendicularly erected. The end face of a ceiling member 3 is butted against the indoor side face of the upper end of the inside face member 2 of the exterior wall panel 1. The airtight sheet 5 is put between a ceiling substrate and the ceiling member 3 to extend it along the face of the ceiling member 3, and the ceiling member 3 is fixed to the ceiling substrate.
