Abstract
A method for manufacturing an electromechanical transducer film including a lower electrode and plural layers of a sol-gel solution film formed on the lower electrode by an inkjet method, the method including the steps of a) modifying a surface of the lower electrode, b) forming a first sol-gel solution film on the surface of the lower electrode by ejecting droplets of a sol-gel solution to the surface of the lower electrode, and c) forming a second sol-gel solution film on the first sol-gel solution film by ejecting droplets of the sol-gel solution to a surface of the first sol-gel solution film. Adjacent dots formed on the surface of the lower electrode by the droplets ejected in step b) overlap each other. Adjacent dots formed on the surface of the first sol-gel solution film by the droplets ejected in step c) do not overlap each other.
