A lens driver includes: an imaging lens; a housing accommodating the lens; a spring member provided between the lens and the housing and holding the lens in the housing movably in the optical axis direction; a coil moving the lens in the optical axis direction; a magnet spaced apart from the coil and moving the lens in the optical axis direction; and a yoke fixed to the magnet and having an L-shaped cross-section when taken along a plane including the optical axis, wherein the yoke is disposed in such a way that an L-shaped corner side is located on the opposite side to the position of the lens where the reaction force of the spring member resulting from the movement of the lens is maximized.
