ABSTRACT:
A piezoelectric substance element has a piezoelectric substance film and a pair of electrodes connected to the piezoelectric substance film on a substrate, and a main component of the piezoelectric substance film is Pb(Zr, Ti)O3, a composition ratio of Zr/(Zr+Ti) is over 0.4 but less than 0.7, the piezoelectric substance film is a film having at last a tetragonal crystal a-domain and a c-domain within a range of ±10° with respect to the surface of the substrate, and a volume rate of the c-domain to the total of the a-domain and the c-domain is equal to or larger than 20% and equal to or smaller than 60%.
