description	The invention provides a lens driving device. The lens driving device (1) is rectangular and can obtain sufficient driving force for driving a large lens body. The lens driving device (1) is provided with a fixed part, a movable part which has a holding part for holding the lens body (6) and which moves along the optical axis direction of the lens body (6) with respect to the fixed part, four coils (30) which are wound around a direction orthogonal to the optical axis and disposed on either the fixed part or the movable part, and four magnets (80) disposed on the other of the fixed part or the movable part with respect to each coil (30). The four coils (30) are arranged at intervals of 90 degrees with the optical axis as the axis, and with respect to the thickness of each coil (30) in the winding axis direction, the coils (30) facing each other are equal to each other, and the coils (30) adjacent to each other are different from each other. The invention also provides a camera device and electronic equipment.
