Abstract
In a method for producing a pressure sensor, a ceramic plate is joined to a shaped ceramic part. The shaped ceramic part has a depression. Around the depression there is provided a thick-layer paste which does not completely surround the depression. As a result, the air can escape from the depression during firing and a subatmospheric pressure can thus be enclosed in the depression.
