This can further prevent detection by the metal detector.
- the metal detector which assumes that the IC tag which concerns on this embodiment is not detected can be used as the metal detector which detects nonferrous metal, for example. This is because, as described above, the dipole antenna may be formed of non-ferrous metals such as silver, copper, and aluminum.
- the detection sensitivity is preferably not detected when, for example, MUK-500 manufactured by Nikka Densetsu Co., Ltd. is used as a metal detector. This device has a detection sensitivity that can detect a SUS ball with an outer diameter of 1.5 mm or more as the smallest detectable substance.

- the cover 4 and the adhesive 5 are not essential, and may not be provided.
- IC tags according to Examples 1 to 5 and Comparative Examples 1 and 2 were prepared as follows. In these examples and comparative examples, the substrate and the IC chip are the same but the dipole antenna is different. Here, five types of antenna shapes shown in FIGS. 4 to 8 were prepared, and three types of materials were prepared. The dotted lines in FIG. 4 to FIG. 8 indicate the path L, and the numerical values indicate the lengths X and Y of the outline. In addition, a polyethylene terephthalate film having a thickness of 50 ⁇ m was prepared as a substrate and a cover, a dipole antenna was disposed between the substrate and the cover, and fixed with the above-described rubber-based pressure-sensitive adhesive. Then, the IC tags according to Examples 1 to 5 and Comparative Examples 1 and 2 were prepared as shown in Table 1 below. As described below, the antennas of the example and the comparative example are made of nonferrous metals.
- the detection level in this device is 0-12. Specifically, it is as follows. That is, when using a SUS304 ball, this device can not detect a ball with a diameter of 1 mm, but can detect a ball with a diameter of 2 mm or more. The detection level is 8 when a ball with a diameter of 2 mm is detected, and 12 when a ball with a diameter of 3 mm is detected. On the other hand, a detection level of 0 means that this metal detector can not detect at all. That is, the closer the detection level is to 0, the more impossibility of detection by this metal detector.
- R / L was 1.5 or more, and the detection levels were all 0. That is, it was not detected at all by the metal detector.
- R / L was lower than Examples 1 to 3 and was 1 or less, but was 0.1 or more.
- the detection level by the metal detector was 3. That is, although at a slight level, it is detected but usable for some applications.
- R / L was lower than 0.1, and the detection level was 12. That is, it is a level that can be reliably detected by the metal detector. Therefore, in the evaluation based on R / L, it was found that Examples 1 to 5 were all superior to Comparative Examples 1 and 2.

以下、本発明に係るICタグの一実施形態について、図面を参照しつつ説明する。図1は、本実施形態に係るICタグの平面図、図2は図1の断面図である。但し、図1は説明の便宜のため、カバーを省略している。図1及び図2に示すように、本実施形態に係るICタグは、矩形状に形成されたシート状の基材1と、この基材1上に配置されたICチップ2及びダイポールアンテナ3と、これらICチップ2及びダイポールアンテナ3を覆う矩形状に形成されたシート状のカバー4と、を備えている。そして、基材1とカバー4とは、粘着剤5によって接着されている。以下、これら各部材について詳細に説明する。
本実施形態に係るダイポールアンテナ3は、次のような物性及び電気特性を有している。この点について、図3を参照しつつ説明する。同図に示すように、まず、ダイポールアンテナ3の両端部S1,S2間の抵抗値R(Ω)、及び、このダイポールアンテナ3に沿ってダイポールアンテナ3の両端部S1,S2を繋ぐ経路の長さであって、ICチップ2を通過しない経路(以下、アンテナ経路という:図3の破線)の長さL(cm)を設定したとき、本実施形態に係るダイポールアンテナ3は、以下の式(1)を充足する。なお、アンテナ経路は、ダイポールアンテナ1の線幅の中心を通る経路である。
0.1≦R/L≦2.5 (1)
1.5≦R/L≦2.5 (2)
本実施形態に係るICタグが検出されないことを想定する金属探知機は、例えば、非鉄金属を検出する金属探知機とすることができる。これは、上記のように、ダイポールアンテナが銀、銅、アルミニウム等の非鉄金属で形成されることがあることによる。そして、検出感度としては、例えば、金属探知機として、ニッカ電測株式会社のMUK-500を用いたときに、検出されないことが好ましい。この装置は、検出できる最小の物質として、外径が1.5mm以上のSUSの球を検出できる検出感度を有している。したがって、一例として、本実施形態に係るICタグが検出されない金属探知機として、非鉄金属に対し、上記のような検出感度を有する金属探知機を規定することができる。但し、これは一例であり、鉄を検出する金属探知機を基準とすることもできる。
以上のように、本実施形態に係るICタグによれば、ダイポールアンテナ3が上記式(1)を充足するように構成されているため、金属探知機で検出されるのを防止することができる。
以上、本発明の一実施形態について説明したが、本発明は上記実施形態に限定されるものではなく、その趣旨を逸脱しない限りにおいて、種々の変更が可能である。そして、以下に示す複数の変形例は適宜組合わせることが可能である。
上述したダイポールアンテナ3の形状は、一例であり、上記式(1)を充足する限りは、種々の形状にすることができる。また、ICタグの形状、つまり、基材1やカバー4の形状も特には限定されず、上記のような長尺状のほか、矩形状、円形状、多角形状など、用途に合わせて種々の形状にすることができる。また、基材1とカバー4とを同形状にしなくてもよい。
上記実施形態では、基材1とカバー4との間の全面に亘って、粘着剤5が塗布されているが、これに限定されるものではない。例えば、基材1とカバー4の周縁にのみゴム系粘着剤5を塗布し、ICチップ2及びアンテナ3が粘着剤5によって囲まれるようにすることもできる。また、カバー4及び粘着剤5は、必須ではなく、設けないようにすることもできる。
以下のように、実施例1~5及び比較例1,2に係るICタグを準備した。これら実施例及び比較例において、基材及びICチップは同じであるが、ダイポールアンテナが相違している。ここでは、図4~図8に示す5種類のアンテナ形状を準備し、3種類の材料を準備した。図4~図8の点線は経路Lであり、数値は外形の長さX,Yを示している。また、基材及びカバーとして、厚みが50μmのポリエチレンテレフタレートフィルムを準備し、ダイポールアンテナを基材とカバーとの間に配置し、上述したゴム系粘着剤により固定した。そして、実施例1~5及び比較例1,2に係るICタグを以下の表1に示すように準備した。以下のように、実施例及び比較例のアンテナは非鉄金属で構成されている。
金属探知機として、ニッカ電測株式会社製MUK-500を用い、上記実施例及び比較例を検知できるかを試験した。この装置における検知レベルは0~12である。具体的には次の通りである。すなわち、SUS304の球を用いた場合、この装置では、直径が1mmの球は検知できないが、直径2mm以上の球が検知できる。そして、直径2mmの球を検知したときの検知レベルは8であり、直径3mmの球を検知したときの検知レベルは12である。一方、検知レベルが0とは、この金属探知機での検出が全くできないことを意味する。すなわち、検知レベルが0に近いほど、この金属探知機での検出ができなくなることを意味する。
