ELECTRIC CURRENT SENSOR DEVICE

Abstract: an electric current sensor device includes a first detector including first and second magnetic detection elements that detect magnetism generated by a current flowing through a first conductor, the first detector detecting a current of the first conductor based on results of the elements, and a second detector including third and fourth detection elements that detect magnetism generated by the second conductor, the second detector detecting a current of the second conductor based on results of the third and fourth elements. the first conductor includes a first wide portion with a first width through which a current flows in a first direction, and a first narrow portion through which a current flows in a second direction, whose width is a second width narrower than the first, and the first and second elements are arranged in a stacking direction of the first narrow portion, and side by side along the surface.
