Piezoelectric component with outer contacting, having gas-phase deposition, method for manufacturing the component and use of the component

A piezoelectric component, comprising:

• at least one stack-type piezoelement having, in the stacking direction,
• at least one electrode layer with electrode material extending to at least a first lateral surface section of the piezoelement,
• at least one further electrode layer with further electrode material, and
• at least one piezoelectric layer with piezoelectric material arranged between electrode layers;
• and
• a first electrical insulation layer, applied to the first lateral surface section of the piezoelement;
• having at least one electrical through-contact enabling electrical contacting of the electrode layer, the electrical through-contact having at least one electrically-conductive gas phase deposition layer applied directly to the at least one electrode layer.

A method for manufacturing a piezoelectric component, comprising:

• providing at least one stack-type piezoelement having an electrode layer, at least one further electrode layer and at least one piezoelectric layer arranged between the electrode layers, with the electrode layer extending up to a lateral surface section of the piezoelement;
• applying at least one electrical insulation layer to the surface section such that the electrode layer is freely accessible;
• applying an electrical through-contact with at least one gas phase deposition layer to the electrode layer by a gas phase deposition method;
• and
• applying an outer electrode to indirectly contact the electrode layer indirectly via the electrical through-contact and the outer electrode and the further electrode layer are electrically insulated from one another.
