Those parts of the wet-paper-side batt layer (30c) which are located around the seam part (12) contain small pieces (40a) of a sheet-form nonwoven fabric destroyed by needle punching, the small pieces (40a) being dispersed within the range of the thickness of the batt layer. At least part of the fibers of the batt layer pass through holes of the small nonwoven-fabric pieces (40a), and the small nonwoven-fabric pieces (40a) are thermally fusion-bonded to fibers of the batt layer.
