Abstract
To render possible a high-quality, yet cost-effective provision suitable for mass production of a piezoelectric pressure transducer (1) with at least one piezoelectric measuring element (3, 3′, 3″) arranged on a housing base part (2), which measuring element is connected on the opposite side to a diaphragm (4), the measuring element (3, 3′, 3″) is fixed on an electrode sheet (5, 5′, 5″, 5″′) or directly on the base part 2 or the diaphragm 4, wherein the electrode sheet (5, 5′, 5″, 5″′) wraps conductively and positively as well as in a manner fixing the layers around a contact pin (7) insulated with respect to the base part (2) and projecting outwards.
