Abstract
An electromechanical conversion element having high connection reliability and an actuator equipped with the electromechanical conversion element. The electromechanical conversion element includes: a displacement part capable of expanding and contracting by application of voltage and having electrode forming faces and an adhesion face which are disposed adjacent to each other; and external electrodes on the electrode forming faces, in which lead electrodes for applying voltage to the displacement part are bonded to bonding regions provided in the external electrodes, and a driven member capable of being driven by the expansion and contraction of the displacement part is bonded to the adhesion face by an adhesive. The electromechanical conversion element further includes bleed flow blocking parts on the electrode forming faces at points closer to the adhesion face than ends of the bonding regions located on the same side as the adhesion face.
