Abstract
A piezoelectric component includes a stack of ceramic layers and electrode layers between ceramic layers in the stack. The electrode layers contain copper and the ceramic layers contain lead-zirconate-titanate that is doped with Nb. The ceramic layers are made from a material having a composition of Pb0.988V0.012(Zr0.504+xTi0.472−xNb0.024)O3.000, where −0.05≦x≦0.05.
