Title:
磁界検出素子および信号伝達素子
Document Type and Number:
Japanese Patent JP5055515
Kind Code:
B2
Abstract:
To improve a linearity of a magnetic detection element 7a having a magnetoresistance effect portion lOa composed of a magnetoresistance effect material and a pair of yoke portions 11a, 11b which is composed of a soft magnetic material and respectively arranged so as to be electrically connected to both sides of the magnetoresistance effect portion 10a, and which guides magnetic flux into the magnetoresistance effect portion 10a, a bypass portion 13a which is composed of a soft magnetic material and saturated with magnetic flux at lower magnetic field intensity than the yoke portions 11a, 11b, and which guides a part of the magnetic flux generated in the yoke portions 11a, 11b so as to divert the magnetic flux from the magnetoresistance effect portion 10a is provided.
