PROBLEM TO BE SOLVED: To transmit the information excellent in the transmission reliability even when the kind of an object to be discriminated is different by fitting a discrimination label to the object to be discriminated so as to form a gap part between the object and the discrimination label to absorb the difference in the permittivity generated by the difference in material by the gap part. SOLUTION: A discrimination label 10 provided with an IC chip 12 to store the information of an object 20 to be discriminated and an antenna 14 to receive/transmit the information of the IC chip 12 between the IC chip and a receiver and a transmitter, is fitted through a cylindrical hollow article 24 of approximately square section in the plan view so as to form a gap part 22 between the object 20 to be discriminated and the discrimination label 10. The difference in permittivity generated by the difference in material of a part to fit the discrimination label 10 of the object 20 to be discriminated is absorbed by the gap part 22, the frequency to be received/transmitted between the antenna 14 and the receiver and the transmitter is difficult to generate the deviation, and the information excellent in the transmission reliability can be transmitted even when the kind of the object 20 to be discriminated is different. |
