摘要
An electromechanical transducer element includes a first electrode, an electromechanical transducer film, and a second electrode. The electromechanical transducer film is a {100} preferentially oriented polycrystalline film. A sum of an orientation degree ρ{111} of {111} plane and an orientation degree ρ{100} of {100} plane is in a range of not less than 0.0002 and not greater than 0.25. At least two diffraction peaks of a plurality of diffraction peaks separated in diffraction peaks derived from {200} plane or {400} plane obtained by the θ-2θ measurement of the electromechanical transducer film according to the X-ray diffraction method attribute to a tetragonal a-domain structure and a tetragonal c-domain structure, respectively. A value of Sc/(Sa+Sc) is not greater than 20%, where Sa represents an area of a diffraction peak attributing to the tetragonal a-domain structure and Sc represents an area of a diffraction peak attributing to the tetragonal c-domain structure.
