Abstract:
A laminated nonwoven fabric includes first to third nonwoven fabrics and an adhesive sandwiched between at least the second nonwoven fabric and the third nonwoven fabric. The second nonwoven fabric contains second fibers and is laminated on the first nonwoven fabric containing first fibers, and the third nonwoven fabric contains third fibers and is laminated on the second nonwoven fabric on an opposite side to the first nonwoven fabric. An average fiber diameter of the first fibers is larger than that of the second fibers. The second nonwoven fabric has first and second regions which exist mixedly with each other, and a density of the second fibers in the second region is lower than that in the first region. A part of the adhesive is present between a portion of the first nonwoven and a portion of the third nonwoven fabric which face the second region.
