Title:
MAGNETIC SENSOR, MANUFACTURING METHOD THEREOF, AND THE CURRENT DETECTOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/080470
Kind Code:
A1
Abstract:
This magnetic sensor is provided with: a substrate, two magnetoresistance effect elements which are connected to a power source terminal and have the same magnetosensitive direction; two magnetoresistance effect elements which are connected to a ground terminal and have the same magnetosensitive direction; and a bias coil which includes a first bias applying unit which applies a bias magnetic field to a first region in which one of the magnetoresistance effect elements connected to a power source terminal and one of the magnetoresistance effect elements connected to a ground terminal are arranged, and a second bias applying unit which applies a biased magnetic field to a second region in which the other of the magnetoresistance effect elements connected to a power source terminal and the other of the magnetoresistance effect elements connected to a ground terminal are arranged. The difference between the cross-sectional area of the first bias applying unit and the cross-sectional area of the second bias applying unit is 35.4% or less.
