Beschreibung
Zusammenfassung:	A laminated nonwoven fabric includes a first nonwoven fabric that comprises first fibers, and a second nonwoven fabric that comprises second fibers. The second nonwoven fabric is laminated on the first nonwoven fabric. An average fiber diameter D1 of the first fibers and an average fiber diameter D2 of the second fibers satisfy a relation of D1>D2. In viewed from a side of a principal surface of the second nonwoven fabric being not opposed to the first nonwoven fabric, a total area of first portions of the second fibers superimposed on the first fibers and existing on the nearer side than the first fibers is larger than a total area of second portions of the second fibers existing and superimposed on voids S of the first nonwoven fabric formed of the first fibers.
