description A lens driving part according to an embodiment of the present invention comprises: a coil located on a substrate; a sensing part disposed so as not to overlap the coil along first and second directions in which the substrate expands; a first magnet facing the coil along a third direction perpendicular to the first and second directions; and a second magnet facing the sensing part along the third direction, wherein a first gap between the substrate and the first magnet and a second gap between the substrate and the second magnet along the third direction may be different from each other. Thus, the present invention can provide the lens driving part that can be provided in a thin form while maintaining driving force for lens movement. 실시예에 따른 렌즈 구동부는 기판에 위치하는 코일, 상기 기판이 확장되는 제1 방향 및 제2 방향을 따라 상기 코일과 중첩하지 않도록 배치되는 센싱부, 상기 제1 방향 및 상기 제2 방향과 수직을 이루는 제3 방향을 따라, 상기 코일과 마주하는 제1 마그넷, 그리고 상기 제3 방향을 따라 상기 센싱부와 마주하는 제2 마그넷을 포함하고, 상기 제3 방향을 따라 상기 기판과 상기 제1 마그넷 사이의 제1 간격과 상기 기판과 상기 제2 마그넷 사이의 제2 간격은 서로 다를 수 있다.
