Document Type and Number:
WIPO Patent Application WO/2017/002554
Kind Code:
A1
Abstract:
The present invention provides a nonwoven fabric that has a good feel and that makes it possible to achieve sufficiently good cushioning properties over a long period of time. The nonwoven fabric (2) is provided with: a base section (22) that is spread in a flat manner and that comprises a first surface and a second surface opposite each other; and a plurality of protrusions (21) that protrude from the first surface of the base section (22) in the thickness direction. Each of the protrusions (21) is provided with a peripheral surface section (21W) that rises from the first surface of the base section (22) in the thickness direction and a peak surface section (21T) comprising a peak surface formed on the vertex of the protrusion (21). The fiber density of the peripheral surface section (21W) is higher than the fiber density of the peak surface section (21T). At least part of a peak surface peripheral edge part (21C) of the peak surface section (21T) is configured as a thickest section (21CM) having the thickest thickness of the nonwoven fabric (2).
