摘要： In a nonwoven fabric, uniaxially oriented bodies each including a thermoplastic resin layer and first and second adhesive layers respectively stacked on both surfaces of the thermoplastic resin layer and having melting points lower than that of a thermoplastic resin constituting the thermoplastic resin layer are warp-weft laminated with the first or second adhesive layer interposed between the uniaxially oriented bodies in such a manner that orientation axes thereof intersect each other. The nonwoven fabric has a mass per unit area of 5 to 13 g/m2, a layer composition ratio of the first adhesive layer, the thermoplastic resin layer, and the second adhesive layer in each of the uniaxially oriented bodies is 20/60/20 to 30/40/30, and an average value of bending resistances by a cantilever method is less than or equal to 50 mm.
