PROBLEM TO BE SOLVED: To make the electronic tag lightweight and fit it to an article such as tableware by easy adhesion by molding resin, which seals a circuit part and a loop antenna, in a hollow shape along the outward shape of the loop antenna. SOLUTION: The electronic tag 20 is equipped with a main control part, a storage part, a signal conversion part, a modulation part, a demodulation part, a transmitting antenna, and a receiving antenna. The electronic tag 20 is fitted to the hill part of the reverse bottom surface of the tableware, etc., and the storage part is stored with the code, charge, etc., of food served on the tableware, etc., as tag information. Then the resin 33 for sealing the circuit part and loop antenna of this electronic tag 20 is molded in the hollow shape (daughnut shape) along the outward shape of the loop coil antenna 32. This electronic tag 20 is fitted inside the cylindrical hill part 42 formed on the reverse bottom surface of the tableware 41 and adhered and reinforced by using an adhesive, etc., at need for, for example, a restaurant automatic account system. |
