To provide a radio IC tag capable of easily corresponding to a change in the design of an antenna pattern.
The radio IC tag 1 includes an IC chip 3 mounted on an adhesive surface of a base sheet 2, and a unicursal antenna pattern 4 formed by unicursally drawing on the adhesive surface of the base sheet 2 using a conductive line. The IC chip 3 has at least two terminals 5 to which the conductive line is electrically connected, and the unicursal antenna pattern 4 starts from a positive electrode side terminal 5 of the IC chip 3, draws a first antenna loop 6 and then, returns to the positive electrode side terminal 5, and starts from a negative electrode side terminal 5 of the IC chip 3, draws a second antenna loop 6 and then, returns to the negative electrode side terminal 5.
