A cleaning tool is formed by bundling a plurality of water-disintegrable cords to have a holding part in which the cords are joined to one another with a holding material wound therearound and bonded thereto by a water-soluble adhesive, and a cleaning part in which the cords are positioned independently from one another. Each cord is formed by twisting a water-disintegrable sheet such as a fiber entangled nonwoven fabric of pulp fibers, rayon fibers, and the like entangled by water-jet processing.
