Abstract
A piezoelectric element is provided. The piezoelectric element includes a piezoelectric layer made of a perovskite compound containing sodium, potassium, lithium, niobium and tantalum and bismuth manganate. The piezoelectric element may also include electrodes for applying a voltage to the piezoelectric layer. The piezoelectric layer may contain 0.25 to 1 mol % of bismuth manganate relative to the perovskite ceramics.
