Abstract
A multilayer nonwoven fabric includes a first fiber layer and a second fiber layer laminated and arranged on a first surface of the first fiber layer. A plurality of groove portions are formed along a prescribed direction in a shape depressed in a thickness direction of the multilayer nonwoven fabric. A plurality of raised ridge portions are formed adjacent to the plurality of groove portions in a shape projected in the thickness direction. The basis weight of the raised ridge portion is greater than the basis weight in regions, which include the bottoms of the groove portions. The second fiber layer including each of the plurality of raised ridge portions is in such a shape that a surface, on the side of the first fiber layer, of the second fiber layer is projected in the same direction as the direction in which the second surface of the first fiber layer is projected.
