The driving assembly includes: a driving magnet member; auxiliary magnet members arranged on opposing sides of the driving magnet member and arranged to have polarities different from a polarity of the driving magnet member in a first direction; and a driving coil including portions extending along boundaries between the driving magnet member and the auxiliary magnet members. ## Claims ### Claim 1 A camera module, comprising: a lens barrel accommodating one or more lenses disposed in an optical axis direction; a first driving assembly configured to move the lens barrel in the optical axis direction; and a second driving assembly configured to move the lens barrel in a direction perpendicular to the optical axis direction, wherein the second driving assembly comprising, a first driving magnet and a second driving magnet respectively fixed relative to the lens barrel; a plurality of first driving coils facing the first driving magnet in a first direction; and a second driving coil facing the second driving magnet in a second direction perpendicular to the first direction, wherein the plurality of first driving coils is disposed along the second direction, and wherein the first direction and the second direction are each perpendicular to the optical axis direction. ### Claim 2 (depends on 1) The camera module according to claim 1, wherein the plurality of first driving coils comprises: a 1-1 driving coil and a 1-2 driving coil respectively facing one surface of the first driving magnet, wherein the one side of the first driving magnet has different polarities on the side facing the 1-1 driving coil and the side facing the 1-2 driving coil. ### Claim 3 (depends on 2) The camera module according to claim 2, wherein the other side of the first driving magnet has a polarity opposite to the one side. ### Claim 4 (depends on 2) The camera module according to claim 2, wherein the second driving coil comprises: a 2-1 driving coil and a 2-2 driving coil arranged side by side in the first direction and each facing one surface of the second driving magnet. ### Claim 5 (depends on 4) The camera module according to claim 4, wherein the one side of the second driving magnet has different polarities on the side facing the 2-1 driving coil and the side facing the 2-2 driving coil, and wherein the other side of the second driving magnet has a polarity opposite to the one side. ### Claim 6 (depends on 1) The camera module according to claim 1, wherein the first driving magnet comprises: a first magnetizing portion formed on a surface facing the plurality of first driving coils; and a second magnetizing portion formed on a side opposite to the first magnetizing portion; wherein the first magnetizing portion has different polarities based on a polarity boundary line parallel to the optical axis direction. ### Claim 7 (depends on 6) The camera module according to claim 6, wherein the second magnetizing portion has a polarity opposite to that of the first magnetizing portion, and wherein the first magnetizing portion and the second magnetizing portion are formed integrally. ### Claim 8 (depends on 1) The camera module according to claim 1, wherein the first driving assembly comprises: a third driving magnet fixed relative to the lens barrel; and a third driving coil facing the third driving magnet in a direction perpendicular to the optical axis direction. ### Claim 9 (depends on 8) The camera module according to claim 8, further comprises: a housing accommodating the lens barrel; a first frame movable in the optical axis direction with respect to the housing; a second frame movable in the first direction with respect to the first frame; and a third frame that is movable in the second direction with respect to the second frame and to which the lens barrel is coupled. ### Claim 10 (depends on 9) The camera module according to claim 9, wherein a plurality of ball members is disposed between the first frame and the second frame or between the second frame and the third frame. ### Claim 11 (depends on 10) The camera module according to claim 10, wherein at least one of the first frame, the second frame, and the third frame comprises a groove in which at least one of the plurality of ball members is accommodated. ### Claim 12 (depends on 9) The camera module according to claim 9, wherein the first driving magnet and the second driving magnet are disposed in the third frame. ### Claim 13 (depends on 12) The camera module according to claim 12, wherein the plurality of first driving coils and the second driving coil are fixed to the housing. ### Claim 14 (depends on 13) The camera module according to claim 13, wherein the plurality of first driving coils and the second driving coil are disposed on a substrate surrounding at least one side of the housing. ### Claim 15 (depends on 9) The camera module according to claim 9, wherein the third driving magnet is disposed in the first frame, and wherein the third driving coil is fixed to the housing.
