A bulky sheet comprising a fiber aggregate formed by water needling of a fiber web is disclosed. The bulky sheet has a number of projections and depressions comprising the fiber aggregate. The projections and the depressions are formed both by rearrangement of the constituting fibers of the fiber aggregate by water needling of the fiber aggregate and by the multiple bending manner of the fiber aggregate along the thickness direction thereof. The projections and the depressions retain the shape thereof by themselves. |
