In a wristbhaving a label-like structure, fracturing notches for preventing unauthorized use are positioned where the two ends of the band are to be glued together. If temporary peeling of the glued ends is attempted, the wristband breaks reliably and it is difficult to return it to the original state. If fracturing notches (11) are formed on either a first winding region (6) or a second winding region (7), which are positioned at left and right ends of the printing region (5). The wristband is configured so that a ring shape can be formed by overlapping and adhering the adhesive layer on the rear surface of one of shape, the first winding region (6) or the second winding region (7) onto the other winding region. An adhesion position check mark (15, 16) is formed on either the first winding region (6) or the second winding region (7).
