Claim 2:
3. The actuator according to claim 1, wherein:
at least one base electrode comprises:
a first base electrode;
a second base electrode disposed spaced apart from the first base electrode; and
an intermediate base electrode disposed between the first base electrode and the second base electrode, wherein:

the one or more counter electrodes include a plurality of counter electrodes respectively disposed between the first base electrode and the intermediate base electrode and between the second base electrode and the intermediate base electrode;
the first base electrode includes a first surface facing the intermediate base electrode, the first surface having a first protrusion-and-recess shape and being covered by a first insulating layer;
the second base electrode includes a second surface facing the intermediate base electrode, the second surface having a second protrusion-and-recess shape and being covered by a second insulating layer;
the intermediate base electrode includes a third surface facing toward the first base electrode, the third surface having a third protrusion-and-recess shape engageable with the first protrusion-and-recess shape and being covered by a third insulating layer; and
the intermediate base electrode further includes a fourth surface facing toward the second base electrode, the fourth surface having a fourth protrusion-and-recess shape engageable with the second protrusion-and-recess shape and being covered by a fourth insulating layer.
