Abstract:
An object of the present invention is to provide a bimorph piezoelectric film that enables the production of touch panels and the like that are less influenced by pyroelectric noise due to temperature change, and exhibit high transparency.The present invention provides a bimorph piezoelectric film comprising in sequence a first piezoelectric film, a tackifier layer or an adhesive agent layer, and a second piezoelectric film, the first piezoelectric film and the second piezoelectric film being disposed in such a manner that their surfaces on which electric charges of the same polarity are generated by a temperature increase are each outward-facing, the first piezoelectric film and the second piezoelectric film each having a total light transmittance of 90% or more, and a total haze value of 8.0% or less.
