1. Piezoelectric acceleration transducer comprising an assembly consisting of a flexible element which is made of a piezoelectric material and is provided with two external electrodes, and which is secured to a support, the assembly being mounted on a carrier plate, wherein:

  • a) the support consists of two nonconductive, plate-shaped supporting components, between which the flexible element is arranged;

    b) the supporting components are connected mechanically to the carrier plate by mechanical points of contact in such a way that a principal axis of sensitivity of the flexible element lies in the same plane as the carrier plate;

    c) the two supporting components are each provided with an electrically conductive coating in a respective area of contact with a respective external electrode of the flexible element;

    d) to establish an electrical connection with the carrier plate, the electrically conductive coating on each of said supporting components extends to at least one of said mechanical points of contact between the supporting components and the carrier plate; and

    e) the mechanical points of contact between the supporting components and the carrier plate are configured as electrical points of contact.
