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. The base board is disposed on the other side of the magnet across the coil board and includes 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. In the fixed unit, a metal-particle-containing resin portion containing metal particles unevenly distributed in a resin covers at least one of a first conductive portion and a second conductive portion.
