Abstract
A first spacer has an arrangement surface on which a wireless IC tag is arranged, and an auxiliary antenna that resonates with electromagnetic wave used for wireless communication is provided on a surface opposite to the arrangement surface of the first spacer. A second spacer is provided opposite to the first spacer with the auxiliary antenna interposed therebetween. The first spacer and the auxiliary antenna are provided with a groove (opening) as an adjuster for resonance frequency so that the second spacer forms a bottom of the groove. Application to a plurality of communication frequencies is made possible by changing an arrangement position of the wireless IC tag with respect to the adjuster.
