To provide a sensor device capable of suppressing unbalance in a distribution of magnetic flux density in a flux-concentrating part.SOLUTION: A first step part 53 includes: a first sensor opposing part 54 that is a portion opposed to a magnetic sensor 70; a first proximal end side bend part 55 that is positioned nearer to a first ring part side of a first flux-concentrating part 52 than the first sensor opposing part 54; and a first distal end side bend part 56 that is positioned nearer to a distal side of the first flux-concentrating part 52 than the first sensor opposing part 54. A second step part 63 includes: a second sensor opposing part 64 that is a portion opposed to the magnetic sensor 70; a second proximal end side bend part 65 that is positioned nearer to a second ring part side of a second flux-concentrating part 62 than the second sensor opposing part 64; and a second distal end side bend part 66 that is positioned nearer to a distal side of the second flux-concentrating part 62 than the second sensor opposing part 64. The magnetic sensor 70 is sandwiched between the first sensor opposing part 54 and the second sensor opposing part 64.SELECTED DRAWING: Figure 3 【課題】集磁部における磁束密度の分布の偏りを抑制することができるセンサ装置を提供する。【解決手段】第１段差部５３は、磁気センサ７０に対して対向する部位である第１センサ対向部５４と、第１センサ対向部５４よりも第１集磁部５２の第１リング部側に位置する第１基端側折曲部５５と、第１センサ対向部５４よりも第１集磁部５２の先端側に位置する第１先端側折曲部５６とを有している。第２段差部６３は、磁気センサ７０に対して対向する部位である第２センサ対向部６４と、第２センサ対向部６４よりも第２集磁部６２の第２リング部側に位置する第２基端側折曲部６５と、第２センサ対向部６４よりも第２集磁部６２の先端側に位置する第２先端側折曲部６６とを有している。磁気センサ７０は、第１センサ対向部５４と第２センサ対向部６４との間に挟み込まれている。【選択図】図３
