Bimorph-type piezoelectric film

An object of the present invention is to provide a bimorph-type piezoelectric film, the bimorph-type piezoelectric film being capable of providing a highly transparent touch panel or the like that is not easily affected by a pyroelectric noise caused by a temperature change. The present invention provides a bimorph-type piezoelectric film including a first piezoelectric film, a gluing agent layer or an adhesive layer, and a second piezoelectric film in this order. The first piezoelectric film and the second piezoelectric film are arranged so that surfaces on which charges having the same polarity are generated due to an increase in the temperature face outside respectively. The bimorph-type piezoelectric film has a total light transmittance of 90% or more and a total haze of 8% or less.
