Abstract
A piezoelectric device includes a vibration plate, and a first piezoelectric element and a second piezoelectric element that vibrate the vibration plate. The first piezoelectric element and the second piezoelectric element include a piezoelectric layer extending between the first piezoelectric element and the second piezoelectric element. In a region between the first piezoelectric element and the second piezoelectric element in the piezoelectric layer, a first opening portion and a second opening portion are formed in a second direction intersecting a first direction in which the first piezoelectric element and the second piezoelectric element are disposed so as to interpose a vibration suppressing portion, which is a portion of the piezoelectric layer.
