Abstract
Provided are a multilayer nonwoven fabric having a meltblown nonwoven fabric layer and a spunbonded nonwoven fabric layer, the multilayer nonwoven fabric having high strength and high water pressure resistance, and a method for producing the same. The multilayer nonwoven fabric includes three or more layers, wherein two outermost layers are spunbonded nonwoven fabric layers, at least one inner layer is a meltblown nonwoven fabric layer, and a resin that forms the spunbonded nonwoven fabric layer has a melting endotherm ΔH, as measured from a melting endothermic curve which is obtained by holding the resin at −10° C. for 5 minutes under a nitrogen atmosphere and then increasing the temperature at a rate of 10° C./min with a differential scanning calorimeter (DSC), of 90 J/g or less.
