Claim 3:
4. The actuator according to claim 1, wherein:
the plurality of base electrodes comprise:
a first base electrode;
a second base electrode disposed spaced apart from the first base electrode; and
a plurality of intermediate base electrodes arranged in sequence between the first base electrode and the second base electrode;

the one or more counter electrodes include a plurality of counter electrodes, the plurality of counter electrodes respectively disposed between the first base electrode and one of the intermediate base electrodes, between one of the intermediate base electrodes and another of the intermediate base electrodes, and between the second base electrode and one of the intermediate base electrodes;
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;
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;
each one of the intermediate base electrodes that is disposed between adjacent ones of the intermediate base electrodes includes a fifth surface facing toward the first base electrode, the fifth surface having a fifth protrusion-and-recess shape and being covered by a fifth insulating layer; and
each one of the intermediate base electrodes that is disposed between adjacent ones of the intermediate base electrodes includes a sixth surface facing toward the second base electrode, the sixth surface having a sixth protrusion-and-recess shape and being covered by a sixth insulating layer.
