PROBLEM TO BE SOLVED: To provide an RFID tag capable of improving antenna efficiency with a simple configuration.SOLUTION: An RFID tag includes: an antenna 3 for communicating signals with a reader/writer; and IC chip 1 connected with the antenna 3. The RFID tag includes a plurality of connection terminals 5A and 5B in an inner part relative to an outer peripheral edge on an insulation layer on which the antenna 3 is formed, and includes an annular antenna formation area in an all outer peripheral area or an almost all outer peripheral area on the insulation layer, having width in inside and outside directions corresponding to distance between the outer peripheral edge on the insulation layer and the connection terminals 5A and 5B. The antenna 3 is formed in a loop shape so that a conductor line circles around inside the antenna formation area, starting at the one connection terminal 5A as a start point and ending at the other connection terminal 5B as an end point.SELECTED DRAWING: Figure 1 【課題】簡素な構成でアンテナ効率の向上を図ることができるＲＦＩＤタグを提供する。【解決手段】リーダー／ライタと信号の送受信を行うためのアンテナ３と、アンテナ３が接続されるＩＣチップ１と、を備え、アンテナ３が形成される絶縁層上の外周端縁よりも内側部分に複数の接続端子５Ａ，５Ｂを備え、絶縁層上の外周端縁と複数の接続端子５Ａ，５Ｂとの間の距離を内外方向の幅として絶縁層上の外周全域又は外周略全域に環状のアンテナ形成領域を備え、アンテナ３は、一方の接続端子５Ａを始点とし、他方の接続端子５Ｂを終点としてアンテナ形成領域内を導体ラインが周回するようにループ状に形成されている。【選択図】図１
