摘要：
A liquid-firing head includes a nozzle firing a liquid drop; a liquid chamber communicating with the nozzle; a vibration plate which acts as a wall of the liquid chamber; and an electrode facing the vibration plate. The vibration plate is deformed by an electrostatic force, and, thereby, the liquid drop is fired through the nozzle. A groove for forming a gap between the electrode and the vibration plate is formed in the electrode.
