Abstract: A lens drive device includes a movable unit, a fixed unit, and a support portion. The movable unit includes a magnet and a lens holder for holding a lens. The fixed unit includes a coil board and a base board. The coil board includes a coil facing the magnet and a coil wiring connected thereto. The base board is disposed opposite to the magnet across the coil board and includes a base wiring and an opening through which the optical axis of the lens passes. The support portion relatively movably connects the movable unit to the fixed unit and supports the movable unit to the fixed unit. A first conductive portion conductively connecting the coil wiring and the base wiring in the fixed unit is disposed away from an opening periphery of the opening to an outside in a radial direction.
