Accordingly, in the longitudinal direction, the adhesive area A forms a width decreasing section in the portion on the first end 4 a side with respect to the easily breakable portion 5 a that continuously decreases from the first end 4 a side towards the second end 4 b side. Meanwhile, the portion on the second end 4 b side with respect to the easily breakable portion 5 a forms a width increasing section that continuously increases from the first end 4 a side towards the second end 4 b side.
