Abstract:
1. An actuator comprising: a substrate having a first face; a plurality of first electrically-conductive layers provided so as to extend in a first direction and to be disposed adjacent to each other in a second direction intersecting the first direction in the first face; a piezoelectric body layer having a first portion formed so as to cover at least a portion of each of a plurality of the first electrically-conductive layers, and a second portion other than the first portion; a second electrically-conductive layer having a third portion which extends along the second direction so as to overlap with at least a portion of each of the first electrically-conductive layers, when viewed from the direction perpendicular to the first face, and continuously cover a plurality of the first portions, and a fourth portion, which is electrically connected to the third portion, is formed over the second portion of the piezoelectric body layer and extends in the first direction; a first lead wiring having a fifth portion which is formed over the fourth portion of the second electrically-conductive layer and extends in the first direction; and a protective film formed so as to cover at least a portion of the first lead wiring, wherein the piezoelectric body layer has a plurality of first opening portions provided so as to extend in the first direction and to be disposed adjacent to each other in the second direction, and the first portion of the piezoelectric body layer is a portion sandwiched between the first opening portions.
