Abstract
A magnetic core is shaped in a ring having a gap and disposed to surround a conductive wire. When an electric current flows in the conductive wire, a magnetic field is generated in the gap. A sensor package includes a Hall element and a lead frame, which are embedded in a resin mold. The sensor package is disposed in the gap to produce an output signal corresponding to the magnetic field in the gap. The Hall element is positioned in the center of the gap, that is, at the position which is the same distance from the end surfaces of the magnetic core.
