Abstract
The invention relates to a piezoelectric multilayer component as an intermediate, which comprises a stack of piezoelectric layers arranged on top of one another. The stack comprises an active region having electrode layers arranged between the piezoelectric layers and at least one inactive region, wherein the active region on the end product of the piezoelectric multilayer component is provided for the purpose of deforming when a voltage is applied to the electrode layers. The inactive region contains at least one sacrificial layer which comprises an electrically insulating material and a metal, wherein the metal can diffuse at least partially from the sacrificial layer into the piezoelectric layers of the inactive region by heating the multilayer component.
