摘要：
A piezoelectric element having a piezoelectric film and one pair of electrodes being in contact with the piezoelectric film on a substrate, wherein the piezoelectric film has a structure in which a lead-containing piezoelectric film and a lead-free piezoelectric film are laminated, and in the piezoelectric film, a layer furthest from the substrate and a layer closest to the substrate are lead-free piezoelectric films.
