A wireless IC tag, to which data can be written by using an IC tag introducing machine, said wireless IC tag can ensure the communication distance required for writing and reading data in the wireless IC tag formed in a dimension that does not intensively affect the strength of the material for building a construction and is provided with antennas with performance of excellent directionality, is provided. The wireless IC tag 1 according to the present invention is characterized in that an RFID tag module 4 is mounted on the columnar ferrite core 2 and a primary antenna 31 having been connected with the RFID tag module and a pair of secondary antennas 32, 33 are wound around the circumferential surface of the plate shapedferrite core 2. |
