Summary:PROBLEM TO BE SOLVED: To easily and inexpensively detect the flaking, cracking or deformation of concrete of a manhole ceiling from the ground through the use of a wireless tag.SOLUTION: Antenna wiring of a wireless tag is formed on a concrete surface of a manhole ceiling. The wireless tag is configured by connecting the antenna wiring and an antenna terminal of a wireless tag circuit part together. A trial of reading of the wireless tag is performed from a reader on the ground, and the presence or absence of deterioration of the manhole ceiling is determined depending on whether or not the reading can be performed. 【課題】無線タグを利用し、マンホール天井のコンクリートの剥落または亀裂または変形を地上から容易かつ低コストで検知する。【解決手段】マンホール天井のコンクリート面に無線タグのアンテナ配線を形成し、該アンテナ配線と無線タグ回路部のアンテナ用端子とを接続して無線タグを構成し、地上のリーダから無線タグの読み取りを試行し、読み取りの可否によってマンホール天井の劣化の有無を判定する。【選択図】 図１
