Disclosed is a method of manufacturing an electromechanical transducer layer on a surface of a substrate, including discharging a solution including a source material to form the electromechanical transducer layer from a nozzle of a nozzle plate to coat the solution on the surface of the substrate while applying voltage between the nozzle plate and the substrate to charge the nozzle plate at a first polarity and the substrate at a second polarity opposite to the first polarity such that a split droplet split from a main droplet which is coated on the surface of the substrate becomes charged at the second polarity and is attracted and collected by the nozzle plate; and applying a heat treatment to the substrate on which the solution is coated to crystallize the solution to form the electromechanical transducer layer.
