Abstract: An RFID tag according to the present invention includes a first antenna on which an IC chip is mounted and a second antenna extending from an end of the first antenna in a direction at right angles to the first antenna. The first antenna has an arbitrarily electrical length and the second antenna has an electrical length of ?/2 or an integral multiple of ?/2.

With this configuration of a tag antenna, the second antenna resonates with the first antenna to exhibit a radio wave amplifying effect. Therefore, a long communication distance can be achieved even if the electrical length of the first antenna is chosen to be short or the thickness of the base film is chosen to be thin.
