A manometer that is simply constructed and therefore economical to manufacture and that can, in particular, be utilized even in the case of abrupt changes in pressure and in humid and conductive media, in particular in hydraulic engineering. Provided for in accordance with the invention is that even when using a glass protective/scratch layer 15 covering over the measuring resistances of the manometric cell 9, this glass protective layer can be omitted or removed in the contact region of the connecting wires (leads) 23. In this region, a glass-free casting compound is cast to protect the connection regions. The manometric cell is fixed to a support 19 and protected by the glass-free casting compound 29.

A manometer with a pressure-measuring cell, in particular piezoresistive pressure-measuring cells, that is formed by the top-lying measurement membrane and a bottom base plate joined therewith and provided with an extension stub in a side direction lying transversely to the top and/or bottom side, on which lie the connections provided on the pressure-measuring cell, from which go out electrical connecting lines, with the pressure-measuring cell, at least in the region of its sensor element, being provided with a protective/scratch layer, preferentially consisting of glass, which is removed or omitted in the contact region from the connections lying offset to the measuring membrane, with the connections being covered over with a glass-free casting compound, characterized by the fact that the pressure-measuring cell is flowed about with the glass-free casting material in its contact region, in a part of the height of the transverse-lying lateral direction, whereby the pressure-measuring cell is fixed and held only at its extension stub by means of the glass-free casting material, and supported against a support.
