Adhesive force and elasticity are imparted to these core bodies 1 by impregnating it with water 2. The washing material is provided with a plurality of leaving grains 3 arranged on surfaces of the respective core bodies 1 in order to prevent the respective core bodies 1 each other from being adhered by the adhesive force and retain the shapes of the respective core bodies 1. It is used for washing in the state the adhering force and the flexibility are imparted to the core bodies 1 by impregnating it with water 2 and the foreign matter on the surface of the material to be washed is captured by the adhesive force of the core bodies 1.
