Abstract: A liquid ejection head, comprises a pressure generation chamber communicating with a nozzle opening and a piezoelectric element having a piezoelectric layer and an electrodes. The piezoelectric layer is a perovskite type complex oxide containing bismuth, iron, and cerium. The piezoelectric layer contains the cerium in a proportion of 0.01 molar ratio or more and 0.13 molar ratio or lower based on the total amount of the bismuth and the cerium.
