Abstract
A magnetic detection element includes a magnetoresistance effect portion composed of a magnetoresistance effect material and a pair of yoke portions. The pair of yoke portions is composed of a soft magnetic material and are respectively arranged so as to be electrically connected to both sides of the magnetoresistance effect portion. The pair of yoke portions guides magnetic flux into the magnetoresistance effect portion. The magnetic detection element also includes a bypass portion, which is composed of a soft magnetic material and is saturated with magnetic flux at lower magnetic field intensity than the yoke portions, and which guides a part of the magnetic flux generated in the yoke portions so as to divert the magnetic flux from the magnetoresistance effect portion.
