2 . The camera device of claim 1 , wherein the driving unit is configured to move the first moving part and the second moving part in directions opposite each other with respect to an optical axis.

3 . The camera device of claim 1 , wherein the driving unit moves the first moving part in a first direction and moves the second moving part in a second direction opposite the first direction, and
wherein both the first direction and the second direction are perpendicular to an optical axis direction.

4 . The camera device of claim 1 , wherein the first moving part comprises a housing and a bobbin disposed in the housing and coupled to the lens, and
wherein the driving unit comprises a first coil disposed on the bobbin, and a first magnet disposed on the housing and disposed at a position corresponding to the first coil.

5 . The camera device of claim 4 ,
wherein the driving unit comprises a second coil disposed on the holder, and a second magnet disposed on the housing and disposed at a position corresponding to the second coil.

6 . The camera device of claim 4 , wherein the housing is spaced apart from the fixed part so as to be movable against the fixed part.

7 . The camera device of claim 4 ,
wherein the first moving part comprises an elastic member connecting the housing and the bobbin, wherein the second moving part comprises a terminal coupled to the holder, and wherein the wire connects the elastic member and the terminal.

8 . The camera device of claim 7 , comprising:
a sensing magnet disposed on the bobbin; a correction magnet disposed on the bobbin and disposed opposite the sensing magnet; a sensing substrate disposed on the housing; and a sensor disposed on the sensing substrate and configured to detect the sensing magnet, wherein the elastic member electrically connects the sensing substrate and the wire.

9 . The camera device of claim 8 , wherein the terminal electrically connects the wire and the second substrate.

10 . The camera device of claim 4 , wherein the bobbin is configured to move in an optical axis direction against the housing, when a current is applied to the first coil.

11 . The camera device of claim 1 , wherein the connection substrate is configured to movably support the second moving part.

12 . The camera device of claim 1 , wherein the connection substrate electrically connects the first substrate and the second substrate.

13 . The camera device of claim 1 , wherein the wire is disposed in an optical axis direction,
