Abstract
Disclosed is an electromechanical transducer element including a first electrode disposed on a substrate; an electromechanical transducer film disposed on a first portion of the first electrode; and a second electrode disposed on a second portion of the electromechanical transducer film, wherein an actuator portion formed by laminating the substrate, the first electrode, the electromechanical transducer film, and the second electrode has a stiffness such that, in a cross section of the actuator portion, the stiffness gradually increases from an end portion of the actuator portion to a center portion of the actuator portion.
