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.
