1. An actuator for optical image stabilization, the actuator comprising:
a fixed frame having an internal space;
a moving frame disposed in the internal space of the fixed frame and configured to be movable relative to the fixed frame;
a first driving unit comprising a plurality of magnets disposed on the fixed frame, and a plurality of coils disposed on the moving frame and configured to be movable together with the moving frame relative to the fixed frame; and
a sensor substrate comprising:
a moving part coupled to the moving frame and configured to be movable together with the moving frame relative to the fixed frame; and
an extension substrate extending from one side of the sensor substrate and covering a portion of at least one surface of the fixed frame,
wherein an image sensor is disposed on the moving part of the sensor substrate, and
a control unit is disposed on a portion of the extension substrate covering the portion of the at least one surface of the fixed frame.
