US Patent 11105831 Current sensor

A current sensor detects a current flowing through a current path. The current sensor includes plural sensor elements, and each sensor element has a current path, a magnetic detector, a first magnetic shield and a second magnetic shield. The magnetic detector faces a part of the current path. A part of the current path and the magnetic detector are positioned between the first and second magnetic shields. The second magnetic field, the current path, the magnetic detector and the first magnetic shield are stacked in order along a stacking direction in each sensor element. The plural sensor elements are disposed adjacently to each other in a direction perpendicular to the stacking direction. The current path has a facing part facing the magnetic detector, and a first bent part bending from the facing part toward the second magnetic shield.
