Abstract: Embodiments provide a lens driving unit including a base, a housing supported so as to be movable relative to the base, a magnet located on the housing, a pattern coil part including a pattern coil that is located opposite the magnet, the pattern coil part being located on the base, and a sensor part mounted to the pattern coil part for sensing a position or movement of the housing, and the pattern coil part includes a first layer and a second layer stacked on the first layer, the sensor part being mounted underneath the first layer, and the pattern coil being formed on the second layer. Thereby, manufacturing costs may be reduced owing to a reduction in the number of elements, processes, and process management points.
