Abstract

A layered nonwoven fabric with excellent feel on the skin and liquid permeability, and a method for producing the layered nonwoven fabric. The layered nonwoven fabric includes an upper layer consisting of a first nonwoven fabric and a lower layer consisting of a second nonwoven fabric. The layered nonwoven fabric has a first surface on the first nonwoven fabric side with a plurality of protrusions and recesses and a second surface on the second nonwoven fabric side. The protrusions on the first surface have a higher basis weight than the recesses on the first surface, and the protrusions on the first surface have a lower fiber density than the recesses on the first surface.
