Abstract
A piezoelectric ceramic transducer includes a tubular body and a metal electrode unit. The tubular body is made of a piezoelectric ceramic material, and includes an inner surrounding surface surrounding an extending central axis thereof and defining an axial through hole, an outer surrounding surface surrounding the inner surrounding surface, and a connecting surface connected between the inner surrounding surface and the outer surrounding surface. Any tangent plane of the connecting surface of the tubular body is not perpendicular to the extending central axis. The metal electrode unit includes a first layer formed on the inner surrounding surface, and a second layer formed on the outer surrounding surface.
