A piezoelectric device comprises a piezoelectric element including a piezoelectric layer formed of a complex oxide having a perovskite structure including bismuth, iron, barium, and titanium, and a pair of electrodes placing the piezoelectric layer therebetween. The piezoelectric element is driven with a first drive mode and a second drive mode. In the first drive mode, the piezoelectric element is driven at a first speed, and is held to a first voltage V1 in a first hold process during a first time defined based on a natural period Tc. In the second drive mode, the piezoelectric element is driven at a higher speed than the first speed, and is held to the first voltage V1 in the first hold process during a second time shorter than the first time, and an intermediate voltage Vm is set to be equal to or lower than a voltage corresponding to the coercive electric field Ec.
