PROBLEM TO BE SOLVED: To provide a marking tool having a small height and a simple configuration regardless of enlargement of a communication range of an IC tag by functioning a body member of the marking tool as an auxiliary antenna or an antenna of the IC tag.SOLUTION: The marking tool to be installed on the ground G includes: a flat metal body member 20 having an upper face 22, a lower face 21, and an outer peripheral face 23, where the body member 20 includes a depressed part 41 at a part of the outer peripheral surface 23 from the upper face 22 to the lower face 21, and an IC tag reception part 43 formed in the depressed part 41 at the side of the upper face 22 or the lower face 21; and an IC tag 25 that is disposed in the IC tag reception part 41 and performs communications by an electromagnetic induction method. The IC tag reception part 43 is spaced from a bottom face 42b of the depressed part 43.
【課題】標示具の本体部材をＩＣタグの補助アンテナまたはアンテナとして機能させることで、ＩＣタグの通信距離を大きくしながらも、高さが小さくかつ構造がシンプルな標示具を提供する。【解決手段】地盤Ｇに設置される標示具であって、上面２２、下面２１および外周面２３を有する扁平状で金属製の本体部材２０であって、外周面２３の一箇所には、上面２２および下面２１にわたって凹入部４１が形成され、凹入部４１には、上面２２または下面２１の側にＩＣタグ受入部４３が設けられた、本体部材２０と、ＩＣタグ受入部４１に配置されるＩＣタグ２５であって、電磁誘導方式によって通信を行う、ＩＣタグ２５とを備え、前記ＩＣタグ受入部４３が凹入部４３の底面４２ｂから離隔している、標示具【選択図】図１
