A piezoelectric element, a liquid ejecting head, a liquid ejecting apparatus, and a sensor capable of reducing a leakage current and improving a displacement amount are provided. A piezoelectric element includes a first electrode, a piezoelectric layer provided on the first electrode, and a second electrode provided on the piezoelectric layer. The body layer 70 is formed by a thin film formation process, is made of a complex oxide having a perovskite structure containing bismuth, iron, barium, titanium, and magnesium, and is preferentially oriented in the (100) plane.
