A piezoelectric thin film element, comprising a piezoelectric thin film lamination with at least a lower electrode, a piezoelectric thin film represented by a general formula (NaxKyLiz)NbO3 (0≦x 1≦, 0≦y≦1, 0≦z≦0.2, x+y+z=1), and an upper electrode disposed on a substrate, wherein the piezoelectric thin film has a crystal structure of a pseudo-cubic crystal or a tetragonal crystal or an orthorhombic crystal, or has a composition in which one of these crystals exists or at least two or more of them coexist, and is preferentially oriented to a specific axis smaller than or equal to two axes of these crystals, and in the ratio of component (001) to component (111), volume fraction of the component (001) falls within a range of 60% or more and 100% or less, and the volume fraction of the component (111) falls within a range of 0% or more and 40% or less, in a case that the total of the component (001) and the component (111) is set to be 100%.
