Abstract
The present invention relates to a method for producing piezoelectric multi-layered components (2), which comprises the following steps: applying an electrode material (5) to green sheets (3) containing a piezoelectric material, applying a layer of a first auxiliary material (9) to at least one green sheet (3) containing the piezoelectric material, forming a stack (1), in which the green sheets (3), to which electrode material (5) is applied, are arranged one on top of another, wherein at least one ply of the green sheet (3), to which the layer of the first auxiliary material (9) is applied, is arranged in the stack (1), sintering the stack (1), wherein the layer of the first auxiliary material (9) is thinned, and firing the stack (1), wherein the stack (1) is singulated along the at least one ply into at least two multi-layered components (2).
