摘要： An electromechanical-transducing electronic component includes at least one element array of electromechanical transducer elements. A piezoelectric material of each transducer element is made of a composite oxide having a perovskite structure preferentially oriented to at least one of (100) and (001) planes and has a drop of diffraction intensity in a rocking curve corresponding to at least one of (200) and (002) planes measured at a position (2θ=θmax) of a diffraction peak intensity P where the diffraction intensity is largest in a diffraction intensity peak corresponding to the at least one of the (200) and (002) planes out of diffraction intensity peaks measured by an X-ray diffraction θ-2θ method. ΔP/PAVE is 20% or less where PAVE represents an average of the intensity P in the element array in the piezoelectric material of each transducer element and ΔP represents a maximum difference of the intensity P in the array.

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.
