Title:
CURRENT SENSOR
Document Type and Number:
WIPO Patent Application WO/2018/012034
Kind Code:
A1
Abstract:
A magnetic sensory 130 is arranged in a position overlapping the position of a second electrical wire 180 in the x direction. A magnetic field forming member 140 is a plate-shape member which extends approximately parallel to the plane perpendicular to the z direction. The magnetic field forming member 140 includes an outer surface which faces towards the magnetic sensor 130, and that outer surface 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 a first electrical wire 110 in the z direction, and the fixing member 120 separates and fixes at least a part of the first electrical wire 110, at least a part of the magnetic sensor 130 and at least a part of the magnetic field forming member 140 in positions that overlap in the z direction.
