Abstract
A wireless IC tag includes an IC chip 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 connected to the response circuit, a first protective material hard in nature for covering the IC chip, and a second protective material, softer than the first protective material, for covering at least a part of the antenna, and the antenna is formed in a laminated structure of a plurality of flat members different in toughness so as not to fracture even when the antenna is bent by external forces.
