    Abstract: A magnetic proportional current sensor includes a magnetic-field detection bridge circuit constituted by four magnetoresistive elements having resistance values changed with application of an induced magnetic field from a current to be measured. Each of the four magnetoresistive elements includes a ferromagnetic pinned layer made up of a first ferromagnetic film and a second ferromagnetic film antiferromagnetically coupled to each other with an antiparallel coupling film interposed therebetween, a nonmagnetic intermediate layer, and a soft magnetic free layer. The first ferromagnetic film and the second ferromagnetic film have substantially equal Curie temperatures and have magnetization magnitudes with a substantially zero difference therebetween. The ferromagnetic pinned layers in the three magnetoresistive elements have a same magnetization direction, and the ferromagnetic pinned layer in the remaining one magnetoresistive element has a magnetization direction differing by 180° from the magnetization direction of the ferromagnetic pinned layers in the three magnetoresistive elements.

    Abstract: A current sensor includes magneto-electric conversion elements divided into a first and second group. The first and second groups are positioned so as to interpose a cut formed in a printed circuit board between them. The first and second groups are symmetrically positioned with respect to a first virtual line. The magneto-electric conversion elements in the first and second groups are symmetrically positioned with respect to a second virtual line orthogonal to the first virtual line at a positioning position at which a to-be-measured current path is positioned. The sensitivity axes of each of pairs of magneto-electric conversion elements that are symmetrical with respect to the positioning position are oriented in parallel in the same direction or opposite directions. An inter-element spacing between adjacent magneto-electric conversion elements in the first and second groups is narrower than an inter-group spacing, which is the narrowest spacing between the first and second groups.
