PROBLEM TO BE SOLVED: To provide a wireless IC device capable of reducing a preparation cost of a wrapper, attaching the wrapper even to a small article and suppressing the thickness of a tag formation section.SOLUTION: For example, a notched section 61 without an aluminum deposition film is formed at an end of an article wrapper 60 with an aluminum deposition laminate film and, at the notched section, an electromagnetic coupling module 1 is provided. A wireless IC device is constituted of the electromagnetic coupling module 1 and the aluminum deposition film on the wrapper 60. A magnetic field antenna of the electromagnetic coupling module 1 is joined to the aluminum deposition film on the wrapper 60, so that the whole article wrapper 60 acts as a radiator of the antenna. |
