A piezoelectric multilayer component has a stack of green piezoceramic layers arranged one on top of the other. A first electrode layer is applied onto a piezoceramic layer and contains a first metal. A structured sacrificial layer is applied onto a further piezoceramic layer, adjacent to the first electrode layer in the stacking direction, and contains a higher concentration of the first metal than does the first electrode layer. When the intermediate product is sintered, the first metal diffuses from the structured sacrificial layer to the first electrode layer and in the process leaves cavities which form a weak layer.
