Title: CURRENT SENSOR
Abstract:
A conductor 10 wherein a current Is to be measured flows has: a first conductor section 11A, which is separated from a first virtual plane P11 having a magnetoresistive effect element disposed thereon, and in which the current Is flows in parallel to a first virtual straight line L11A; a second conductor section 12, which intersects the first virtual plane P11, and in which the current Is flows in parallel to a second virtual straight line L12; a bent section 14A, which is provided in a current path between the second conductor section 12 and the first conductor section 11A, and which is bent from the X2 direction parallel to the second virtual straight line L12 to the Y2 direction parallel to the first virtual straight line L11A; and a third conductor section 13A that is provided in a current path between the bent section 14A and the first conductor section 11A. The direction of a magnetic field generated due to the current Is flowing in the second conductor section 12 is perpendicular to the first virtual plane P11.
