Document Type and Number:
Japanese Patent JP4885869
Kind Code:
B2
Abstract:
In a multilayer piezoelectric element comprising a plurality of piezoelectric layers and a plurality of metal layers which are alternately stacked one upon another, the metal layers includes a plurality of high resistance metal layers having a higher electrical resistance than adjacent metal layers on the both sides. The high resistance metal layers are regularly arranged so as to interpose a plurality of different metal layers other than the high resistance metal layers. In another multilayer piezoelectric element in which a plurality of piezoelectric layers and a plurality of metal layers are alternately stacked one upon another, at least one layer of the metal layers is formed by a plurality of partial metal layers disposed between the piezoelectric layers.
