Piezoelectric element and piezoelectric device

摘要

A piezoelectric element is provided with a multilayer body comprising an alternate stack of first internal electrodes and second internal electrodes with a piezoelectric layer in between each two of the first and second internal electrodes. The multilayer body has an outermost piezoelectric layer adjoining the second internal electrode at an extreme end in a stack direction of the multilayer body among the first internal electrodes and the second internal electrodes and constituting one end face in the stack direction of the multilayer body. The whole first internal electrode adjacent in the stack direction of the multilayer body to the second internal electrode adjoining the outermost piezoelectric layer is hidden by the second internal electrode adjoining the outermost piezoelectric layer, when viewed in the stack direction of the multilayer body from the outermost piezoelectric layer side.
