This laminated structure is free from pin holes and has a good waterproof property and a feeling of the porous base material. The thermoplastic resin layer to be employed in the laminated structure is selected to have a melt viscosity of 5.times.10.sup.4 poise (measurement conditions: load=10 kgf, nozzle diameter=1 mm, nozzle length=1 mm: JIS K 7311, 10) at a temperature lower than an extrusion temperature by 20.degree. C. The laminated structure is suitable for use as a medical waterproof fabric, an inner bag of a coverlet and the like products.
