A liquid ejecting head includes: a piezoelectric element including a piezoelectric layer; a pressure compartment substrate in which a pressure compartment is provided; and a diaphragm that applies pressure to liquid in the pressure compartment by vibrating by being driven by the piezoelectric element. The pressure compartment substrate, the diaphragm, and the piezoelectric element are stacked in this order in a stacking direction. A neutral plane of a stacked body made up of the piezoelectric element and the diaphragm is located inside the piezoelectric layer. Of two regions obtained by dividing the piezoelectric layer with respect to the neutral plane, a region located closer to the diaphragm is defined as a lower region, and a region located farther from the diaphragm is defined as an upper region. A piezoelectric constant of the lower region is less than a piezoelectric constant of the upper region.
