Claim:
1. A method for producing a ceramic multilayer element, the method comprising: forming a plurality of multilayer segments in a green state, wherein each multilayer segment has a plurality of ceramic layers in the green state and a plurality of electrode layers, wherein, while forming the plurality of multilayer segments, the multilayer segments are not located one on top of the other but are separate from each other, wherein each multilayer segment is formed separately by pressing together the plurality of ceramic layers and electrode layers at one pressing force; stacking the plurality of multilayer segments in the green state one on top of the other after forming the plurality of multilayer segments; pressing together the stacked multilayer segments in the green state thereby forming a multilayer element that is in the green state, wherein the one pressing force is greater than a pressing force applied during the pressing together of the stacked multilayer segments; and sintering the multilayer element that is in the green state thereby forming the ceramic multilayer element, the ceramic multilayer element comprising the ceramic layers and electrode layers arranged one on top of another, wherein at least one or more of a temperature at which the stacked multilayer segments are pressed together, the pressing force applied during the pressing together of the stacked multilayer segments, and a duration of the pressing together of the stacked multilayer segments, are adjusted such that the sintered ceramic multilayer element includes a boundary region between the stacked multilayer segments, the boundary region having a tensile strength that causes the boundary region to function as a predetermined breakage region, wherein the tensile strength is determined by adjusting at least the pressing force applied during the pressing together of the stacked multilayer segments.
