PROBLEM TO BE SOLVED: To provide an RFID(Radio Frequency Identification) tag and the attaching structure by which both of sealing performance and mechanical strength against the periphery are provided, costs are lowered and communication by electromagnetic waves is easily performed. SOLUTION: A cylindrical antenna coil 2 and a semiconductor IC chip 4 are integrally formed and sealed with a sealing body 5 formed of a non-magnetic material. The outer peripheral surface of the sealing body 5 is covered with a metallic cylindrical body 6 whose both ends are opened, provided with a clearance 6a in a longitudinal direction. |
