The invention relates to a method of producing a fibrous sheet， wherein the method comprises a step of: forming a plurality of fiber granules by entangling the fibers into granules; disposing the plurality of fiber granules in a three-dimensional direction into a sheet; and bonding the plurality of fiber granules together with heat-fusible fibers contained in the fiber granules by heating the fiber granules disposed in . the three-dimensional direction; wherein the arrangement of the fiber granules into a sheet comprises: keeping the fiber granules on a pair of rollers; and discharging the fiber granules from a gap between said pair of rollers. A fibrous sheet 1 which comprises a plurality of fiber granules 2 each made up of entangled fibers 3. The plurality of fiber granules 2 have been three-dimensionally entangled with one another by fibers 3a protruding therefrom. The plurality of fiber granules 2 have been bonded with heat-fusible fibers contained in the plurality of fiber granules 2. The fibrous sheet 1 is produced by a method comprising entangling fibers 3 to form a plurality of fiber granules 2， three-dimensionally arranging the plurality of fiber granules 2， and heating the plurality of fiber granules 2 to bond the plurality of fiber granules 2 with the heat-fusible fibers.
