    摘要: Disclosed is an electromechanical transducer element that includes an electromechanical transducer film formed of a complex oxide (PZT) including lead (Pb), zirconium (Zr), and titanium (Ti). The electromechanical transducer film is formed by laminating plural PZT thin films until a thickness of the formed electromechanical transducer film becomes a predetermined thickness. When an atomic weight ratio (Pb/(Zr+Ti)) of average Pb included in the formed electromechanical transducer film is denoted by Pb(avg) and an atomic weight ratio (Pb/(Zr+Ti)) of Pb in any one of laminate interfaces of the plural PZT thin films is denoted by Pb(interface), the Pb(avg) is greater than or equal to 100 atomic percentage (at %) and less than or equal to 110 atomic percentage (at %), and a fluctuation ratio ΔPb=Pb(avg)−Pb(interface) of Pb in the laminate interface is less than or equal to 20 percent.
