摘要： An electric current sensor device includes a first detector (21) including a first magnetic detection element (21a) and a second magnetic detection element (21b) that detect magnetism generated by a current flowing through a first conductor (11), and the first detector detecting a current of the first conductor (11) based on detection results of the first magnetic detection element and the second magnetic detection element, and a second detector (22) including a third magnetic detection element (22a) and a fourth magnetic detection element (22b) that detect magnetism generated by a current flowing through the second conductor (12), and the second detector detecting a current of the second conductor (12) based on detection results of the third magnetic detection element and the fourth magnetic detection element. The first conductor (11) includes a first wide portion (11w) through which a current flows in a first direction (D1) and whose width is a first width (w1), and a first narrow portion (11n) through which a current flows in a second direction (D2) and whose width is a second width (w2) narrower than the first width (w1), and the first magnetic detection element (21a) and the second magnetic detection element (21b) are arranged in a stacking direction of a surface of the first narrow portion (11n), and are arranged side by side in a direction along the surface of the first narrow portion (11n).

摘要： An electric current sensor device (7) includes a conductor (11), a detector (21) detecting magnetism generated by a current flowing through the conductor (11), a board (14) on which the detector (21) is mounted, and a heat dissipation member (16) coupled to the conductor (11) in a thermally conductive manner, the heat dissipation member dissipating heat of the conductor (11). The heat dissipation member (16) is disposed on a side opposite to the board (14) with respect to the conductor (11) in a stacking direction (Dz), and is coupled to the board (14) in a thermally conductive manner.
