To provide a roll of loop coil that eliminates the necessity of burying work in metal detection such as vehicle detection in a parking lot.SOLUTION: A roll of loop coil 1 used for metal detection is one piece formed by connecting thin boards 11, 12, 13, 14, 15, 16, 17 by welding, in the shape of a loop as a whole. The thin boards 15 and 16 form a part extending toward outside from the loop shape. An end part 15a of the thin board 15 and an end part 16a of the thin board 16 are connected by a feeder wire to a detector that performs metal detection, while the thin boards 15 and 16 are in an electrically non-connected state due to an insulator 18.SELECTED DRAWING: Figure 1

    【課題】 駐車場における車両検知のような金属検知において、埋設を不要にした1巻のループコイルを提供する。【解決手段】 金属検知に用いられる1巻のループコイル1は、薄板11,12,13,14,15,16,17が熔接によって繋げられた1本のものであり、全体としてはループ形状をなし、薄板15及び薄板16はループ形状から外に向かって延びている部分を形成し、薄板15の端部15aと薄板16の端部16aが金属検知を行う検知器にフィーダ線で接続される一方で、薄板15と薄板16とは絶縁体18によって電気的に非接続状態になっている。【選択図】 図1
