<p>A wireless IC tag (1) includes an IC chip (11) with a response circuit for receiving a signal sent from an interrogator and transmitting a response signal in response to the received signal, a rectangular antenna (91) connected to the response circuit, a first protective material (14) hard in nature for covering the IC chip (11), and a second protective material (15), softer than the first protective material (14), for covering at least a part of the antenna (91), and the antenna (91) is formed in a laminated structure of a plurality of flat members different in toughness so as not to fracture even when the antenna (91) is bent by external forces.</p> |
