Patent ID: 8604668

Claim:
A piezoelectric element comprising: a support body having a displacing part that is capable of undergoing displacement in a thickness direction; a lower electrode layer having a lower main electrode body and a lower electrode wire part, the lower main electrode body being provided on the support body in a region inside an outer peripheral edge of the displacing part in a plan view when the support body is viewed in the thickness direction of the displacing part, and the lower electrode wire part being connected to the lower main electrode body and provided across a region outside and the region inside the outer peripheral edge of the displacing part; a first piezoelectric layer provided on the lower main electrode body in the region inside the outer peripheral edge of the displacing part in the plan view, the first piezoelectric layer being formed at a first position that does not overlap with the outer peripheral edge of the displacing part in the plan view; an upper electrode layer provided across the region outside and the region inside the outer peripheral edge of the displacing part in the plan view, at least a part of the upper electrode layer being layered on the first piezoelectric layer and insulated from the lower electrode layer; and a second piezoelectric layer provided on the support body to cover at least a part of the lower electrode wire part.
