Abstract: A piezoelectric element which is a single-layer or laminated piezoelectric element has a first electrode, a second electrode, and a piezoelectric ceramic layer. The first electrode and second electrode contain silver by 50 percent by weight or more. The piezoelectric ceramic layer is placed between the first electrode and second electrode, and constituted by a polycrystalline substance of alkali niobate piezoelectric ceramic containing at least one alkali earth metal being calcium, strontium, or barium, and silver. According to this constitution, the electrical resistance and piezoelectric property can be improved, and consequently high reliability and good piezoelectric characteristics can be achieved.
