Abstract
A sensor for detecting a physical variable, including: —a sensor element for outputting an electrical signal dependent on the physical variable, —a substrate carrying the sensor element, —a printed circuit board, conducting the electrical signal, on the substrate, and —an embedding compound, in which the sensor element is completely embedded and the printed circuit board is at least partly embedded, —wherein at least one compensation element is embodied in the embedding compound, by which compensation element a mechanical stress caused by an element of the sensor at least partly embedded in the embedding compound is counteracted.
