Abstract

PURPOSE:To eliminate the step of bonding and to improve the moldability of a piezoelectric bimorph by forming a piezoelectric material having two-phase structure by thermal pressing or coating and then polarizing it. CONSTITUTION:Vinylidene fluoride-ethylene trifluoride copolymer or high molecular material having it as a main ingredient is thermally pressed in a film shape or coated in solution state on a film-shaped high molecular and inorganic composite piezoelectric material to form a piezoelectric material having two-phase structure. Thereafter, it is polarized. Reverse polarity piezoelectric property is imparted thereto by forming two-phase structure with the vinylidene fluoride-ethylene trifluoride copolymer and high molecular and inorganic composite piezoelectric material and thereafter applying DC electric field thereto to polarize it, and a both-side bimorph structure can be obtained.
