In an implantable pressure measuring device, in particular for measuring an intracranial pressure, is provided. In order to simplify production, it is proposed that the pressure measuring device comprises an implant housing and a pressure measuring sensor, which is arranged in the implant housing, with one or more load cell(s). The implant housing has an opening. The pressure measuring sensor is provided with a coating applied directly to the load cell(s). The pressure measuring sensor is arranged in the implant housing in such a way that the opening provides direct access to the load cell(s) for a fluid surrounding the pressure measuring device and therefore the surrounding pressure acts directly on the coated load cell(s) of the pressure measuring sensor. The coating is produced from a para-xylylene-based polymer material.
