An actuator includes a piezoelectric layer, a vibration plate, and a reduction inhibition layer. The piezoelectric layer includes an oxide material. The vibration plate is disposed below the piezoelectric layer, and configured to deform when the piezoelectric layer deforms. The reduction inhibition layer is disposed between the piezoelectric layer and the vibration plate, and configured to inhibit reduction reaction in the piezoelectric layer.
