Abstract

A pressure measuring device comprises a carrier, a base which is connected to the carrier, and a pressure sensor which is mounted on the base, wherein a bottom base area of the pressure sensor is greater than a top base area of the base, the pressure sensor being protected against thermomechanical stresses by an end of the base, which is facing away from the pressure sensor, the end being adhesively bonded into a recess in the support by an adhesive bond.
