Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a coin-shaped IC tag which easily adjusts resonance frequency, can secure a wide transmission range, and can acquire a stable operation even when it is used by being projected and rolled in machinery.SOLUTION: A coin-shaped IC tag 10 includes an inlet 1 provided with an IC chip 5 and a coil antenna 4, and a pair of circular arc-shaped metal parts 2. In the coin-shaped IC tag, the pair of circular arc-shaped metal parts is arranged along a peripheral part of the coil antenna of the inlet with opening sides mutually facing each other at a position at which desired resonance frequency can be acquired, and is fixed integrally with the inlet by resin.SELECTED DRAWING: Figure 1 【課題】共振周波数の調整が容易で、広い伝送範囲を確保することができ、機械装置に投入転動させて使用しても安定した動作が得られるコイン形状のＩＣタグを提供することを課題とする。【解決手段】ＩＣチップ５とコイルアンテナ４を備えたインレット１と、一対の円弧状金属パーツ２と、を備えたコイン形状のＩＣタグ１０であって、一対の円弧状金属パーツは、インレットのコイルアンテナの周縁部に沿って、互いに開口側を向かい合わせにして、所望の共振周波数が得られる位置に配置され、樹脂によりインレットと一体に固定されていることを特徴とするコイン形状のＩＣタグ。【選択図】図１
