摘要

An applying liquid is applied to a first electrode by ejecting from a nozzle the applying liquid including a raw material for forming an elecromechanical transducer film, and a film of the applying liquid applied onto the first electrode is dried. The dried film is thermally decomposed and crystallized. At this time, a voltage is applied to an accompanying droplet collecting electrode for collecting a small accompanying droplet accompanying a chief droplet. The accompanying droplet is electrostatically attracted and collected by the accompanying droplet collecting electrode before reaching the first electrode. At this time, the voltage is applied to the accompanying droplet collecting electrode by the voltage applying part after a predetermined period of time has elapsed from when a droplet of the applying liquid has been ejected from the nozzle.
