Title:
MAGNETIC SENSOR
Document Type and Number:
WIPO Patent Application WO/2016/024621
Kind Code:
A1
Abstract:
A magnetic sensor that detects, with high precision, a magnetic signal comprising a mixture of magnetic fields that are directed, respectively, along three orthogonal axes. This invention provides a magnetic sensor that contains a first magnetic sensing unit provided with the following: a first magnetic convergence part comprising a first magnetic convergence member that extends along a first axis and a second magnetic convergence member that is connected to the end of the first magnetic convergence member in the positive direction along the first axis; a second magnetic convergence part comprising a third magnetic convergence member that extends further in the negative direction of a second axis than the end of the second magnetic convergence member in the negative direction along the second axis and a fourth magnetic convergence member that is connected to the end of the third magnetic convergence member in the negative direction along the second axis; a first magnetic sensing part that is positioned between the second magnetic convergence member and the third magnetic convergence member and extends along the second axis; and a second magnetic sensing part that is positioned further in the positive direction along the first axis than the second magnetic convergence member and extends along the second axis.
