Title:

LAMINATED PIEZOELECTRIC ELEMENT AND JETTING APPARATUS USING SAME

Document Type and Number:

WIPO Patent Application WO/2007/037377

Kind Code:

A1

Abstract:

In a laminated piezoelectric element, a plurality of piezoelectric layers and a plurality of metal layers are alternately laminated. The metal layers include a plurality of high resistance metal layers having an electrical resistance higher than electrical resistances of the adjacent metal layers on the both sides. The high resistance metal layers are regularly arranged by sandwiching a plurality of metal layers other than the high resistance metal layers. In another laminated piezoelectric element, a plurality of piezoelectric layers and a plurality of metal layers are alternately laminated, and at least one layer of the metal layers is composed of a plurality of partial metal layers arranged between the piezoelectric layers.
