SENSOR UNIT AND CONDUCTOR DETERIORATION DETECTION DEVICE

To provide a sensor unit and a conductor deterioration detection device that can more appropriately adjust an inter-coil distance in which an excitation coil and a detection coil overlap with each other.SOLUTION: A sensor unit 10 includes: a sensor 11 which includes an excitation coil 13 and a detection coil 14; a case 12 which stores the excitation coil 13 and the detection coil 14 internally in a state where the axial directions Z thereof are in parallel to each other, they are arrayed along the extension direction X of an electric wire W intersecting the axial direction Z and they partially overlap with each other when viewed from the axial direction Z, and fixes one of the excitation coil 13 and the detection coil 14; a holder 15 which holds the other of the excitation coil 13 and the detection coil 14 and is supported so as to be relatively movable along the extension direction X with respect to the case 12; a gear mechanism 16 which relatively moves the holder 15 along the extension direction X in the case 12; and an operation part 17 for operating the gear mechanism 16.SELECTED DRAWING: Figure 7 【課題】励磁コイルと検出コイルとが重なり合うコイル間距離をより適正に調整することができるセンサユニットおよび導体劣化検出装置を提供することを目的とする。【解決手段】センサユニット１０は、励磁コイル１３および検出コイル１４を有したセンサ１１と、励磁コイル１３および検出コイル１４を互いの軸方向Ｚが平行でありかつ軸方向Ｚと交差する電線Ｗの延在方向Ｘに沿って並びつつ軸方向Ｚから見た場合に互いに部分的に重なり合う状態で内部に収容すると共に、励磁コイル１３および検出コイル１４のうち一方を固定するケース１２と、励磁コイル１３および検出コイル１４のうち他方を保持すると共に、ケース１２に対して延在方向Ｘに沿って相対移動可能に支持されるホルダ１５と、ホルダ１５をケース１２内で延在方向Ｘに沿って相対移動させる歯車機構１６と、歯車機構１６を操作するための操作部１７と、を備える。【選択図】図７
