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.

Abstract: A first magnetoelectric conversion element group including magnetoelectric conversion elements, and a second magnetoelectric conversion element group including magnetoelectric conversion elements are arranged across a cutout of a wiring board. The first and second groups are arranged line-symmetrically with respect to a first imaginary line. The elements in the first and second groups are arranged line-symmetrically with respect to a second imaginary line. The first imaginary line and the second imaginary line orthogonally intersect each other at a placement position at which a current path to be measured is placed. The orientation of the sensitivity axis of each of a plurality of magnetoelectric-conversion-element sets having point symmetry about the placement position is parallel or antiparallel. An element spacing, which is spacing between neighboring elements in the first and second groups, is narrower than a group spacing, which is the narrowest spacing between the first and second groups.
