A sensor device includes a sensor element, a supporting member, a substrate, and a bonding wire. The supporting member is electrically connected to the sensor element. The substrate is electrically connected to the supporting member. The bonding wire forms at least part of a connection path that electrically connects the sensor element and the supporting member together. The substrate and an installation member on which the sensor element is installed intersect with each other. The sensor element and the supporting member are separated from each other.

A magnetic core includes a winding core and first and second flanges connected to the winding core. First and second terminal electrodes are connected to a lead frame. The first flange is bonded to the first and second terminal electrodes. Third and fourth terminal electrodes are bonded to the second flange. First and second insulation-coated conductive wires are wound about the winding core. The first and second insulation-coated conductive wires are connected to the first and second terminal electrodes and the third and fourth terminal electrodes. The lead frame is bent so as to rotate the magnetic core by 90 degrees with respect to the lead frame. A magnetic plate is bonded to the magnetic core. The magnetic core is removed from the lead frame by removing the first and second terminal electrodes from the lead frame, thereby providing a common-mode choke coil. The common-mode choke coil having stable electrical performance is produced efficiently by the above method.
