Abstract

PURPOSE:To obtain the piezoelectric or the pyroelectric material having a high piezoelectric constant a pyroelectric constant by a method wherein an electrode consisting of a conductive substance, having a fluidity at a temperature below the melting point for a high molecular material, is provided inside a hollow tube made of an elongated and orientationally polarized tubular high molecular material. CONSTITUTION:Polyvinylidene fluoride resion or polyvinyl fluoride resin is fused and squeezed into a hollow filament, which is elonated and orientationally polarized and turned into a capillary tube having an inside diameter of about 300mum and an outside diameter of about 500mum. Then a aluminum is evaporated on the tube surface, while sodium chloride saturated solution, having a fluidity at a temperature below the melting point of the resin, is injected into the tube and both ends are sealed. After that, a lead wire conductive to the solution is provided without touching the evaporated aluminum film. Through said procedure, a piezoelectric body whose piezoelectric constant is as high as 30X10<-12>C/N is obtained and also a pyroelectric material, having a pyroelectric constant of 3.5X10<-9>C/cm<2>.deg. can be obtained.
