A fibrous sheet containing cotton fibers and at least two kinds of synthetic fibers is disclosed. The synthetic fibers form a nonwoven fabric. The cotton fibers enter a fiber network of the nonwoven fabric and interlace with the fiber network thereby to form a cotton fiber layer on one side of the nonwoven fabric, with part of the cotton fiber layer entering the nonwoven fabric. The synthetic fibers contain a combination of heat fusible fiber (a) and heat fusible fiber (b) having a small thickness than the fiber (a) or a combination of the fiber (a) and a fiber (c) that is not thermally bonded with the fiber (a).
