    摘要： The invention relates to a pressure sensor measuring element (26) for a pressure sensor (10) for detecting the pressure in a combustion chamber of an internal combustion engine during operation of the latter, having a separating diaphragm (54), a plunger (56) for transmitting deflections of the separating diaphragm (54) to a force measuring element (32), and a sleeve (36) which accommodates the plunger (56), is closed by the separating diaphragm (54) at a first end (12) facing the combustion chamber and is designed to hold the force measuring element (32) at the opposite, second end (16). In order to be able to produce the pressure sensor measuring element (26) in a more cost-effective manner with the same functionality, it is proposed to form the plunger (56) in a single piece with the separating diaphragm (54) as a diaphragm/plunger unit (38), wherein the sleeve (36) and the diaphragm/plunger unit (38) are formed from the same metal material.
