A piezoelectric ceramic element includes a top-layer, a bottom-layer and at least one intermediate-layer ceramic sheets stacked to each other for sintering. An alloy layer of silver and palladium is interposed between every two ceramic sheets, and a silver layer is coated on each exposed surface of the top-layer and the bottom-layer ceramic sheets, so as to form a positive and a negative electrode circuit therein. The piezoelectric ceramic element with the silver layer is attached to at least one surface of a metal plate to make a piezoelectric component which is used to make a piezoelectric actuator, loudspeaker or buzzer. |
