Among them, when a multi-directionally laminated layer is opened on the inner side of the adhesive layer, the adhesive for simultaneous application during construction passes through the adhesive layer. In addition, when the reinforcing layer is present, the sheet of the present invention is used as a laminate to apply an adhesive for lamination, and the lamination pressure is laminated by the layers, so that the lamination eye can easily reach the adhesive layer, so it can be passed with fewer steps. In addition, in the case where the adhesive layer and the additive are used, the reinforcing layer is easily absorbed and laminated in such a manner that the lamination dimension or the polyolefin fiber coated on the protective layer is excellent in one degree. Ester fibers and polyolefin fibers are particularly good. It is not used for vertical and horizontal yarns, and can also be laminated with synthetic resin layers. The form of the substrate is preferably a woven fabric or a woven fabric. Specifically, non-woven fabrics made of spunbond, woven long-spun woven fabrics, or woven fabrics can be mentioned, and multidirectional layered fabrics which are laminated in a network form are also preferable. The reason is that when the reinforcing adhesive is sufficiently impregnated into the mesh of the multi-layer laminated fabric of the reinforcing layer, it is easy to make the film of the protective layer make the reinforcing layer inside and adhere when it is between the protective layer and the adhesive layer. The adhesive passes through the net of the multi-directional laminated fabric in one pass, and the two are laminated. There is no adhesive for lamination for lamination between strong layers. Furthermore, the adhesive is adhered to the mesh portion of the multi-layer laminated cloth like the attached layer, so the mesh
