To discover a laminated sheet of a nonwoven fabric and a moisture-permeable film which is capable of preventing stuffiness, which is free from the problem of blocking and also has a beautiful external appearance and besides which withstands long-time use, brings about no falling-off of fibers and causes no disadvantage such as exfoliation between the nonwovn fabric and the moisture-permeable film.
The laminated sheet is formed by laminating the liquid-impermeable and moisture-permeable plastic film and the composite nonwoven fabric. A first nonwoven fabric layer constituted of a nonwoven fabric consisting of fibers having a fiber diameter of 0.5 dtex or less and a second nonwoven fabric layer constituted of a nonwoven fabric consisting of fibers having a larger diameter than ones forming the first nonwoven fabric layer are provided for the composite nonwoven fabric, and the second nonwoven fabric layer of this composite nonwoven fabric is disposed outside, while the plastic film is adhered to the inside of the composite nonwoven fabric layers by a hot-melt adhesive containing SEPS.
