A pressure measuring device comprises a capacitive pressure measuring cell, a process connector including a retaining element, a housing mounted on the process connector, and a sealing element arranged between an inwardly projecting region of the retaining element and the pressure measuring cell. The retaining element is configured with a cap with a base area portion and an outer area portion bent over with respect thereto and fitted over an end face of the process connector. The retaining element is in a material-bonded and/or form-fit manner connected to the process connector exclusively in the bent-over outer area portion so that the base area portion assumes a resilient property.
