To smoothly separate a pressure sensitive adhesive label stuck once and to perform various communication after separation by forming a perforated line in a substrate in such a way that the substrate can be divided into 1st and 2nd areas, laminating a peelable layer between the substrate and a barrier layer in the 1st area and forming a slit in the peelable layer and the barrier layer in a terminal region in which a pressure sensitive adhesive layer is not formed.

A perforated line 7 is formed in a substrate 2 in such as a way that the substrate 2 can be divided into a 1st area which is a release chip 12 for a chit where a seal is stamped and a 2nd area which is a tag 11. In the part of the release chip 12 for a chip, peeling takes place between a peelable layer 5 and a barrier layer 3. The barrier layer 3 stably retain peelability, that is, weak adhesive power between the barrier layer 3 and the peelable layer 5 disposed between the substrate 2 and the barrier layer 3 in the part of the release chip 12 for a chit. In a region 9 in which a pressure sensitive adhesive layer 4 is not formed in the release chip 12 for a chit, a slit 10 is formed in a design printed layer 8, the barrier layer 3 and the peelable layer 5.
