PROBLEM TO BE SOLVED: To provide an IC tag in a UHF band, which can be made thin, can increase a communication range while having flexibility, and can be reduced in size to a degree not degrading workability upon mounting the tag.SOLUTION: The IC tag includes: a metal foil part 20 formed of a metal foil and generating static waves of a high-frequency current on a surface thereof; a dielectric layer 30; and an IC tag main body 40 mounted on the electric layer 30 and communicating with an external communication device, when a high-frequency current is applied to the metal foil part 20, by generating an electro-magnetic coupling with a coil antenna 43. The IC tag main body 40A is mounted on the dielectric layer 30 in such a manner that, when a gradient direction on a surface of the IC tag main body 40A where the coil antenna 43 is present is decomposed into a component in a thickness direction where the metal foil part 20 and the dielectric layer 30 are stacked and a component in a surface direction of the metal foil part 20, the component in the surface direction is larger than the component in the thickness direction.SELECTED DRAWING: Figure 1 【課題】型化を達成し、さらには柔軟性を備えながらも飛距離を伸ばすことができ、さらには取り付けの際の作業性を悪化させない程度に小型化されたＵＨＦ帯域のＩＣタグを提供すること。【解決手段】表面に定在波の高周波電流を生じさせると共に、金属箔を材質として形成される金属箔部２０と、誘電体層３０と、誘電体層３０に取り付けられ、金属箔部２０に高周波電流が流れた場合にコイルアンテナ４３との間で電磁結合を生じさせることで外部の通信装置との間で通信を行うためのＩＣタグ本体４０と、を備え、ＩＣタグ本体４０Ａのうちコイルアンテナ４３が存在する表面の傾斜方向を、金属箔部２０と誘電体層３０とが積層される厚み方向成分と金属箔部２０の表面方向成分とに分けた場合、表面方向成分が厚み方向成分よりも大きくなるように、ＩＣタグ本体部４０Ａが誘電体層３０に取り付けられている。【選択図】図１
