<p>The problem addressed by the present invention is to provide a polymer composite piezoelectric body resulting from dispersing piezoelectric body particles in a polymer matrix, wherein the polymer composite piezoelectric body has high piezoelectric properties. The problem is solved by means of the piezoelectric body particles being lead zirconate titanate, and tetragonal and rhombohedral crystals being present in a mixed manner in each piezoelectric body particle.</p> |
