Abstract
An object is to provide a piezoelectric body having a value indicating a higher performance index (d, e, C, g, and/or k) than aluminum nitride not doped with any element. The piezoelectric body is represented by a chemical formula AlMgMN where X+Y is less than 1, X is in a range of more than 0 and less than 1, and Y is in a range of more than 0 and less than 1.
