摘要： A liquid ejecting head including a fluid channel forming substrate including a pressure generating chamber communicating with a nozzle opening that ejects a liquid droplet and a piezoelectric element. The piezoelectric element has a first electrode, a piezoelectric material layer that is provided on the first electrode and has a perovskite monoclinic structure, and a second electrode formed on the piezoelectric material layer opposite to the first electrode. An angle formed between a direction of an electric field generated between the first and second electrodes and an orientation of a polarization moment of the piezoelectric material layer is greater than an angle formed between the direction of the electric field at a time when the piezoelectric constant of the piezoelectric material layer reaches a maximum level and the orientation of the polarization moment.
