A pressure sensor device for a pressure sensor, in particular a capacitive pressure sensor, having a pressure chamber bounded by a movable sensing membrane and a stationary counterelectrode of the pressure sensor device. The sensing membrane and the counterelectrode each run in the longitudinal direction and the transverse direction of the pressure sensor device. The sensing membrane is directly or indirectly spring-mounted, in particular spring-mounted in two-dimensional fashion, in the pressure chamber relative to the counterelectrode by at least one micromechanical spring element, in particular a plurality of micromechanical spring elements.
