Abstract:
1. An electromechanical transducer comprising: a first electrode mounted on one of a substrate and a base film; an electromechanical transducer film mounted on the first electrode and made of a piezoelectric substance having a perovskite crystal structure; and a second electrode mounted on the electromechanical transducer film, the electromechanical transducer film including a {100} plane preferentially oriented to be orthogonal to a thickness direction of the electromechanical transducer film and having a full width at half maximum corresponding to a {200} plane in an X-ray diffraction measurement curve in 2θ-ω scan that is measured by emitting an X-ray beam onto a surface of the electromechanical transducer film while diffraction angle 2θ is fixed and the X-ray beam is scanned at incident angle ω that changes, the full width at half maximum being not greater than 10 degrees.
