The present invention provides a piezoelectric thin film element with superior
piezoelectric properties in which the condition of the crystal of the piezoelectric
thin film is appropriately controlled, and a manufacturing method thereof, as well
as a inkjet recording head, inkjet printer, or other liquid ejecting apparatus
employing the same. The piezoelectric thin film element 40 comprises a top
electrode 44, a bottom electrode 42, and a piezoelectric thin film
43 formed between the top electrode 44 and the bottom electrode 42,
wherein the piezoelectric thin film 43 is structured so as to comprise a
first layer 431 located nearest to the bottom electrode and second layers
(433-436) that are located nearer to the top electrode than the first layer
and that have thicknesses greater than that of the first layer 431.
