PURPOSE:To permit easy removal of the unnecessary matter sticking to recessed parts by pulling a long-sized base material in a longitudinal direction while exerting the force to restrain the movement in a pulling direction to the front face of the long-sized base material on the side opposite from the tacky surface thereof in the case of pulling apart the tacky surface from the base of the recesses. CONSTITUTION:This method consists in sticking the matter 229 to be cleaned existing on the base 595 of the recesses to the tacky surface provided to the top end of the projecting part projected from the long-sized base material 22 and removing the same from the base 596 while holding the matter 229 stuck to the tacky surface by the tensile force exerted to the base material. The long-sized base material is pulled in the longitudinal direction while the force to restrain the movement in the pulling direction is kept exerted to the surface of the material 222 on the side opposite from the tacky surface thereof. The unnecessary matter in the recesses is thereby surely removed.
