摘要：
The invention provides a piezoelectric polymer material including a helical chiral polymer having a weight average molecular weight of from 50,000 to 1,000,000 and having optical activity, the piezoelectric polymer material having a piezoelectric constant d14 at 25° C. of 10 pC/N or more, a degree of crystallinity obtained by X-ray diffraction of from 40% to 80%, and a haze of from 0.5 to 30.
