A lens driving device has a carrier, a coil, an upper spring, a lower spring, a yoke, a magnet, and a lower member. The carrier is cylindrical and has a hollow part along a vertical direction so that a lens can be carried. The coil is fixed to an outer peripheral surface of the carrier. The upper spring is arranged over the carrier, and fixed to the yoke. The lower spring is arranged below the carrier. The yoke is formed into a box shape having a side wall and an opening on the lower side, and arranged around the carrier. The magnet is arranged in the yoke so as to be opposed to the coil. The lower member is arranged below the yoke. The lower member has a projection part connected to the yoke. The projection part is inserted between an inner surface of the side wall of the yoke and an outer surface of the magnet and connected to the yoke. Thus, the yoke and the lower member can be connected such that space for the magnet to be arranged in the yoke is less affected.
