An inductively operating sensor, particularly for measuring distances and positions of a metallic object, comprising at least a coil, a ferromagnetic or ferritic core and perhaps a housing comprising a sensor element, with the core being embedded in a single or multi-layered ceramic and jointly with the ceramic forming a coil body and with the coil body and the core being connected to each other in a form-fitting fashion. Furthermore, a method is suggested for producing such a sensor.
