%X This paper is to display existence and its conditions to a surface acoustic wave propogating along surface of a half-body of piezoelectric ceramics with a rotation of constant angular velocity. It is found that when the half-body rotates, whether or not a surface acoustic wave, which corresponds to either the Rayleigh wave or the Bleustein-Gulyaev wave on the surface of the half-body without rotation, exists is dependent upon those material parameters of the piezoelectric body. If a surface acoustic wave exists when the piezoelectric body rotates, the results exhibit that the surface wave is dispersive. As an example, finally, some quantitative results of the characteristic relation between the wave speed and the rotation angular velocity are given for the PZT-5H material of piezoelectric ceramics.
