Pressure gauge preferably arranged to function on the outside of a measuring element (1), the measuring element having a central cavity (103) and being constituted by at least two parts (100A-B) which are tightly joined for creation of the cavity, and comprising sensor organs (11-14) for the mechanical state of stress of the measuring element during pressure influence. The two parts of the measuring element (100A-B) are manufactured in planar techniques, preferably by silicon or quarts with the cavity running in the longitudinal direction. The central cavity has a considerably greater height than width. The sensor organs (11-14) have form of piezo-resistive elements arranged near an outer (105) eventually inner surface of the measuring element.
