ABSTRACT:
Disclosed is a method of producing composite piezoelectric materials exhibiting a high flexibility and a high piezoelectric effect, comprising the steps of treating an inorganic dielectric material powder with a latex-containing dispersion so as to coat the surfaces of the powder particles with the rubber particles in a manner to provide encapsulated powder particles, kneading the encapsulated powder particles, shaping the kneaded mass, and polarizing the shaped mass.
