Abstract:
The invention provides a piezoelectric polymer material comprising a helical chiral polymer having a weight average molecular weight of from 50,000 to 1,000,000 and optical activity, the piezoelectric polymer material having: crystallinity as obtained by a DSC method of from 20% to 80%; a transmission haze with respect to visible light of 50% or less; and a product of the crystallinity and a standardized molecular orientation MORc, which is measured with a microwave transmission-type molecular orientation meter at a reference thickness of 50 μm, of from 40 to 700.
