A piezoelectric contains comprises a plurality of piezoelectric particles
made from a piezoelectric material such as lead titanate zirconate and a
dielectric made from a dielectric material, such as a composite
perovskite compound, having a higher dielectric constant then the
piezoelectric material, the dielectric existing in gaps between the
piezoelectric particles. When poling to produce a piezoelectric ceramic,
the poling is uniformly performed, and nearly all of the electric field
is applied to the piezoelectric particles. Thus, the dispersion of the
piezoelectric properties can be reduced, and the piezoelectric properties
can be enhanced.
