摘要：
Provided is a piezoelectric material having a high Curie temperature and satisfactory piezoelectric characteristics, the piezoelectric material being represented by the following general formula (1): A(ZnxTi(1-x))yM(1-y)O3 (1) where A represents a Bi element, M represents at least one element selected from Fe, Al, Sc, Mn, Y, Ga, and Yb; x represents a numerical value of 0.4≦x≦0.6; and y represents a numerical value of 0.17≦y≦0.60.
