摘要： A liquid ejecting head has a piezoelectric element with a first electrode, a piezoelectric layer, and a second electrode. The liquid ejecting head causes pressure changes in a pressure generating chamber communicating with a nozzle opening. The piezoelectric layer has a perovskite structure and is preferentially orientated in a (100) plane. A method for producing the liquid ejecting head includes polarizing the piezoelectric layer by applying an electric field having energy higher than energy required for converting the polarization direction in the direction to the direction and lower than energy required for converting the polarization direction in the direction to the direction when the electric field to be applied to the piezoelectric layer is in the direction vertical to a plane on which the second electrode is provided.
