ABSTRACT:
The pressure sensor (2) comprises a pressure detector element (21) arranged to receive a pressure that is to be measured and to detect it, and a printed circuit (22) connected to the pressure detector element (21) via an electrical connection, and it is characterized in that the electrical connection comprises at least one flexible conductive tongue (29) having a first end (290) connected directly or indirectly to the printed circuit (22) and a second end (291) merely bearing against a corresponding electrical contact (213a) of the pressure detector element (21). In order to ensure good electrical contact, the bearing face (294) of the second end of the or each flexible conductive tongue (29) bearing against the corresponding electrical contact (213a) is polished.
