Claim 7:
8. A surface structure manufacturing method comprising:
integrally manufacturing by stacking a body and a pillar which is a portion of a plurality of three-dimensional micro pillar structures formed at a certain angle with the body, such that a passage for providing wires is formed under the plurality of three-dimensional micro structure of the body, the manufacturing comprising
forming the plurality of three-dimensional micro pillar structures on the body in rows and columns, and
forming the passage along the columns of the plurality of three-dimensional micro pillar structures;

connecting the wires through the passage;
applying a conductive material to the pillar of the plurality of three-dimensional micro pillar structures;
coating an insulating material on the conductive material; and
connecting a first power supply for supplying a positive (+) voltage to first wires among the wires and a second power supply for supplying a negative (−) voltage to second wires among the wires such that the positive (+) voltage and the negative (−) voltage are alternately supplied to the plurality of three-dimensional micro pillar structures in accordance with column positions of the plurality of three-dimensional micro pillar structures formed on the body.
