<p>PROBLEM TO BE SOLVED: To provide a laminate sheet which allows joining without impairing waterproofness and has moisture-permeable waterproofness and a method of joining the laminate sheets.SOLUTION: A laminate sheet 1 includes a sheet body 2 consisting of a moisture-permeable waterproof sheet 10 and a protective sheet 11, stacked together, and a heat fusion film 12 containing a low-melting-point material lower in melting point than the moisture-permeable waterproof sheet 10 and the protective sheet 11, and the heat fusion film 12 is present on the upper, lower and side surfaces of the sheet body 2, on at least one side A of the sheet body 2. The heat fusion film 12 preferably has a laminated structure consisting of a low-melting-point material layer composed of a low-melting-point material and a high-melting-point material layer composed of a high-melting-point material higher in melting point than the low-melting-point material.</p> |
