1. An actuator for a camera comprising:
a housing comprising an interior space;
a guide member, a base, and a carrier stacked in the housing in an optical axis direction;
a first driving unit configured to generate driving force in a first axial direction, perpendicular to the optical axis direction, and in a second axial direction, perpendicular to both the optical axis direction and the first axial direction, the first driving unit comprising a plurality of magnets and a plurality of coils; and
a second driving unit configured to generate driving force in the optical axis direction and comprising a magnet and a coil,
wherein the carrier, the base, and the guide member are configured to be movable together in the first axial direction,
wherein the carrier and the base are configured to be movable together in the second axial direction,
wherein the carrier is configured to be movable relative to the base in the optical axis direction,
wherein the plurality of magnets and the plurality of coils of the first driving unit are disposed to face each other in the optical axis direction, and
wherein the magnet and the coil of the second driving unit are disposed to face each other in the optical axis direction.
