A first lead electrode containing nickel and chromium contacts a second upper electrode containing titanium. Here, since a difference between the normal electrode potential of nickel and chromium and the normal electrode potential of titanium is smaller than a difference between the normal electrode potential of nickel and chromium and the normal electrode potential of iridium, electric corrosion can be made difficult to occur as compared with the case where the first lead electrode containing nickel and chromium contacts a first upper electrode containing iridium. Therefore, a piezoelectric element can be obtained in which an increase in resistance due to the narrowing of the contact area between an upper electrode and a lead electrode for upper electrode or the separation of the lead electrode for upper electrode can be suppressed and which can be driven by a given voltage.
