摘要： A liquid discharge head having a nozzle substrate including a nozzle from which a liquid is discharged in a liquid discharge direction, a pressure chamber communicating with the nozzle, a diaphragm defining a part of wall of the pressure chamber, and a pressure generator on a first surface of the diaphragm opposite to a second surface of the diaphragm facing the pressure chamber, the pressure generator configured to deform the diaphragm. A gap between a first line and a second line is 40 μm or less in a direction perpendicular to the liquid discharge direction, where the first line extends, in the liquid discharge direction, from a displacement center at which the diaphragm deforms with a maximum displacement amount, and the second line extends from a central position of the nozzle in the liquid discharge direction.

摘要： An electromechanical transducer element includes an electromechanical transducer film including a complex oxide that has a perovskite structure containing at least Pb, Zr and Ti; a pair of electrodes disposed to sandwich the electromechanical transducer film; and an insulating protective film covering the electromechanical transducer film and the pair of electrodes. Pb content of the electromechanical transducer film is uniform in a film thickness direction of the electromechanical transducer film, and a density of leak current measured between the pair of electrodes is 4.2×10−6 A/cm2 or less in an environment in which a water vapor pressure is 300 kPa.
