A material sheet assembly in which a label base attached to a release liner by means of an adhesive is set in roll form is used. In a step in which the material sheet assembly is continuously fed out, the release liner is released by leaving the adhesive on the label base, and the release liner is consecutively taken up. By using a noncontact-type printer, printing is effected on the adhesive surface of the label base separated from the release liner to form a printed label. The printed label is in such a form that the printed surface is disposed between the label base and an adherend. The labels can be attached immediately after they are manufactured, and they can be stored or transported by being taken up in roll form while an additional release liner is attached to the printed surface side.
