Title: CURRENT SENSOR
Abstract:
This current sensor 100 is provided with an electrical wire 110 which has a width in the z direction greater than the thickness in the x direction, a magnetic sensor 130, a magnetic field forming member 140 which includes a soft magnetic material, and a fixing member 120. The magnetic field forming member 140 is a plate-shape member which extends approximately in parallel with the plane orthogonal to the z direction, the magnetic field forming member 140 includes a first outer surface 141 which faces towards the magnetic sensor 130, and the first outer surface 141 and the orientation of the sensitivity axis of the magnetic sensor 130 are approximately parallel with the x direction. The fixing member 120 fixes the magnetic sensor 130 and the magnetic field forming member 140 so as to be in close proximity on the same side of the electrical wire 110 in the z direction, and the fixing member 120 separates and fixes the electrical wire 110, the magnetic sensor 130 and the magnetic field forming member 140 in positions that overlap in the z direction.
