  In addition, since the second protrusion 33 is provided, a sufficient thickness of the elastic member 12 can be secured between the water stop member 11 and the installation surface T when the water stop sheet 10 is pressed against the installation surface T. For this reason, the water-stopping property can be improved.

  In addition, as shown in FIG. 7, the length L1 in the surface 32a of the 1st protrusion part 32 is formed longer than the thickness W1 of the water stop member 11. As shown in FIG.

  Thereby, since the length of the elastic member 12 more than the width W1 of the water stop member 11 can be ensured when the water stop sheet 10 is pressed against the installation surface T, the water stop can be improved.

  In addition, the thickness W2 of the tip 32b, which is the thinnest part of the first protrusion 32, is formed to be thicker than the thickness W3 of the fixed part 31.

  Thus, by thickening the 1st protrusion part 32, while being able to ensure the water stop property at the time of pressing the water stop sheet 10 against the installation surface T, by making the fixing | fixed part 31 thin, the diameter at the time of winding can be ensured. Can be small.

  FIG. 9 is a schematic diagram showing a cross section taken along the line AA 'in FIG. In the cross-sectional view of FIG. 9, the waterproof sheet 10 of the present embodiment is part of the inner second protruding portion 33 between the end surface 21 of the waterproof member 11 and the first protruding portion 32 when wound. Has been inserted.
