Summary:PROBLEM TO BE SOLVED: To provide a moisture sensor for suppressing reduction of measuring precision of moisture content contained in a measuring object.SOLUTION: A moisture sensor 10 has a sensor part 30 which is a conductive member wound planarly and mounted on soil 81 as a measuring object. An equivalent inductance of the sensor part 30 changes according to change of a moisture content contained in the soil 81. The moisture sensor 10 detects the moisture content contained the in soil 81 by the equivalent inductance change of the sensor part 30.SELECTED DRAWING: Figure 1 【課題】測定対象物に含まれる水分量の測定精度の低下を抑制する水分センサを提供する。【解決手段】水分センサ１０は、平面状に巻回する導電性部材であって、測定対象物としての土壌８１に取付けられるセンサ部３０を有する。センサ部３０は、土壌８１に含まれる水分量の変化により等価インダクタンスが変化する。水分センサ１０は、センサ部３０の等価インダクタンス変化により、土壌８１に含まれる水分量を検出する。【選択図】図１
