Claim:
1. A method of fabricating an electromechanical transducer film, the method comprising: treating a surface of a first electrode to be liquid-repellent, the first electrode being formed on one surface of a substrate; irradiating the surface of the liquid-repellent first electrode with an energy ray to be lyophilic while moving an irradiation position to form a pair of first shapes and a plurality of second shapes, the plurality of second shapes being provided between the pair of first shapes; forming a pair of alignment marks by applying an application liquid to an area at least including the formed pair of first shapes by landing a plurality of droplets of the application liquid at regular intervals by an inkjet method; detecting a print position based on the formed pair of alignment marks; and forming the electromechanical transducer film by applying a sol-gel liquid to the area in accordance with the plurality of second shapes based on the detected print position, the sol-gel liquid being applied by the inkjet method, wherein the formed electromechanical transducer film is distinct and separate from the formed pair of alignment marks, each of the formed pair of first shapes has a plurality of sides, and a shortest side of each of the formed pair of first shapes is longer than a diameter of the at least one of the plurality of the landed droplets of the application liquid.
