<p>A reliably wide directivity range is achieved even when a subject to which a wireless tag circuit element is to be attached is composed of metal, and excellent information transmission/reception is performed. A wireless tag circuit element (T2) has an IC circuit section (150) for storing information and a tag antenna (ANT2) for transmitting and receiving information, and the element is attached to a subject (110) to which the element is to be attached. The tag antenna (ANT2) has a dielectric substrate (101), which is composed of three or more dielectric substrate surfaces (101a, 101b, 101c) wherein the adjacent surfaces substantially orthogonally intersect with each other to be connected and is arranged to cover the apexes of the subject (110); and a microstrip antenna pattern (105), which is formed on the dielectric substrate (101) on the side opposite to the side where the subject (110) is covered, and is provided with a power feed point (Ps) connected to the IC circuit section (150).</p> |
