1. A shaped body (10) for a pressure sensor, having a membrane (12) and having a supporting section (14) supporting the membrane (12), the membrane (12) being produced at least in sections from a ceramic material by additive manufacturing, and having at least in sections a thickness of more than 0.1 mm and of less than 0.5 mm, and wherein the membrane (12) and the supporting section (14) are each generated from a plurality of printed layers, wherein:
the greatest possible distance between two points lying on the outer circumference of the membrane (12) is less than 18 mm,
in a cross-section of the supporting section (14), the greatest possible distance between two points lying on the outer circumference of the supporting section (14) is less than 25 mm, and
the supporting section (14) is produced, in a region adjacent to the membrane (12) in the circumferential direction, from layers which merge into layers of the membrane (12) without interruption.
