A liquid ejecting head includes a pressure-generating chamber in fluid communication with a nozzle opening and a piezoelectric element having a piezoelectric layer and electrodes provided to the piezoelectric layer. The piezoelectric layer is composed of a complex oxide having a perovskite structure containing bismuth and cerium in the A site of the perovskite structure and at least one metallic element selected from the group consisting of iron, cobalt, and chromium in the B site of the perovskite structure, and the molar ratio of the metallic element or elements in the B site, the bismuth, and the cerium is 1:(1−x):(3x/4).
