A piezoelectric element includes a substrate, a first electrode, a piezoelectric film and a second electrode that are sequentially placed in the above-mentioned order. The piezoelectric film contains oxides of Ba, Bi, Ti, Zr, Fe and Mn and has a perovskite structure, wherein the molar ratio y of Bi relative to the sum of Ba and Bi is 0.001≦y≦0.015, the molar ratio x of Zr relative to the sum of Ti, Zr, Fe and Mn is 0.010≦x≦0.060, the molar ratio z of Fe relative to the sum of Ti, Zr, Fe and Mn is 0.001≦z≦0.015, and the molar ratio m of Mn relative to the sum of Ti, Zr, Fe and Mn is 0.0020≦m≦0.0150, while the relationship between y and z is expressed by 0.90≦y/z≦1.10.
