To enable reduction in size, and obtain detection values in a stable manner. A first magnetoelectric conversion element group (A15) made up of magnetoelectric conversion elements (15a through 15d), and a second magnetoelectric conversion element group (B15) made up of magnetoelectric conversion elements (15e through 15h) are arranged across a cutout (17) of a wiring board (16). The first and second magnetoelectric conversion element groups are arranged line-symmetrically with respect to a first imaginary line (IL1). The magnetoelectric conversion elements (15) in the first and second magnetoelectric conversion element groups are arranged line-symmetrically with respect to a second imaginary line (IL2). The first imaginary line and the second imaginary line orthogonally intersect each other at a placement position (PP) at which a current path (CB) 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 either parallel or antiparallel. An element spacing (DA1), which is spacing between neighboring magnetoelectric conversion elements in the first and second magnetoelectric conversion element groups, is narrower than a group spacing (DG1), which is the narrowest spacing between the first and second magnetoelectric conversion element groups. |
