    摘要: A layered body includes: a polymer film (A), the polymer film (A) including an organic piezoelectric material having a weight average molecular weight of from 50,000 to 1,000,000, having a standardized molecular orientation MORc at a reference thickness of 50 μm of from 1.0 to 15.0 as measured by a microwave transmission molecular orientation analyzer, having a degree of crystallinity of from 20% to 80% as measured by a DSC method, and having an internal haze of 50% or less with respect to visible light; and a peelable protective film (B) that contacts one main face of the polymer film (A). The maximum indentation depth hmax on a face of the protective film (B) that contacts the polymer film (A) is from 53 nm to 100 nm as measured by a nanoindentation method.
