ABSTRACT:
A piezo-electric ceramic composition which is favorably used for such applications as ceramic filter, vibrator applying ultrasonic waves, piezo-electric buzzer, piezo-electric ignition unit, ultrasonic wave motor, piezo-electric fan and piezo-electric sensors such as acceleration sensor, knocking sensor, AE sensor, etc. and is particularly used as a member for constituting a piezo-electric actuator. The piezo-electric ceramic composition is a composite perovskite compound which contains, as metal components, Pb, Zr, Ti, Zn, Sb as well as Sr and Ba, or Pb, Zr, Ti, Zn, Sb and at least either one or Sr or Ba, and Ni and Te, wherein when the composition by the molar ratio of metal elements is expressed by the following general formula (1),
