A pressure sensor has a substrate with conductor tracks for contact-connecting electrical components. The pressure sensor has a measuring element for converting a mechanical measurement variable into an electrical signal and a signal converter for processing the electrical signals from the measuring element further. Furthermore, the pressure sensor has a first diaphragm which, together with the substrate, forms a first closed cavity which contains an inert filling medium. At least one side of the measuring element of the pressure sensor, which comprises an active surface, has direct contact with the filling medium in the first cavity. The signal converter is arranged on the substrate in the form of an unhoused integrated circuit.
