FLEXIBLE SENSOR AND MEASURING DEVICE

To prevent deformation of a tip portion of a coil body in a state where no stress is applied.SOLUTION: A flexible sensor (10) that detects a physical quantity of an object to be measured while surrounding the object to be measured includes a detecting body (1) of which a tip portion (11) having elasticity is bent to form, and that detects the physical quantity of the object to be measured, and a main body portion (2) to which a base end portion (13) of the detecting body (1) is attached and having an insertion passage (70) through which the tip portion (11) of the detecting body (1) is inserted, in which the insertion passage (70) is bent to form a same shape as the tip portion (11) of the detecting body (1) that is in a state where the tip portion (11) is not stressed.SELECTED DRAWING: Figure 1 【課題】応力がかかっていない状態におけるコイル体の先端部の変形を防止すること。【解決手段】測定対象を取り囲んだ状態で測定対象についての物理量を検出するフレキシブルセンサ（１０）は、弾性を有する先端部（１１）が曲げられて形成され、測定対象についての物理量を検出する検出体（１）と、検出体（１）の基端部（１３）が取り付けられると共に、検出体（１）の先端部（１１）を挿通する挿通路（７０）を有する本体部（２）と、を備え、挿通路（７０）は、検出体（１）の先端部（１１）に応力がかかっていない状態の先端部（１１）と同じ形に曲げられて形成されている。【選択図】図１
