at least one support member, which supports the housing such that the housing is movable with respect to a base, over which the housing is disposed, in second and/or third directions and which conductively connects at least one of the upper and lower elastic members to the printed circuit board, the at least one support member being integrated with two conductive wires,
wherein the upper elastic member includes first to fourth upper elastic members, which are separated from one another and which are conductively connected to the printed circuit board, and fifth and sixth upper elastic members, which are separated from each other and which are conductively connected to the lower elastic member, and
wherein the first to sixth upper elastic members are separated from one another.

2. The lens moving apparatus according to claim 1 , wherein the lower elastic member includes first and second lower elastic members, which are separated from each other, and the at least one support member includes a first support member in which the two conductive wires are connected to one of the first to fourth upper elastic members.

3. The lens moving apparatus according to claim 2 , wherein the first support member includes an electrical insulating coating member sheathing the two conductive wires such that the two conductive wires are conductively isolated from each other by means of the coating member.

4. The lens moving apparatus according to claim 2 , wherein the at least one support member includes a second support member in which one of the two conductive wires is connected to one of the first to fourth upper elastic members, and a remaining one of the two conductive wires is connected to one of the fifth and sixth upper elastic members.

5. The lens moving apparatus according to claim 4 , wherein the second support member includes an electrical insulating coating member sheathing the two conductive wires such that the two conductive wires are conductively isolated from each other by means of the coating member.

6. The lens moving apparatus according to claim 4 , comprising a conductive member connecting the upper elastic member and the lower elastic member.

7. The lens moving apparatus according to claim 6 , wherein the conductive member includes a first conductive member connecting one of the fifth and sixth upper elastic members and one of the first and second lower elastic members.

8. The lens moving apparatus according to claim 7 , wherein the conductive member includes a second conductive member connecting the other of the fifth and sixth upper elastic members and the other of the first and second lower elastic members.

9. A lens moving apparatus, comprising:
