摘要： A lens drive device formed in a substantially quadrangular shape may include a movable body holding a lens, a fixed body movably holding the movable body, and a drive mechanism for driving the movable body in the optical axis direction. The drive mechanism may include first drive magnets respectively disposed on four side faces of the lens drive device, a second drive magnet for restraining inclination which is disposed on at least one of four corners of the lens drive device, and a drive coil which is wound around in a substantially octagonal shape. Magnetic flux passing through the drive coil at one of the four corners of the lens drive device is different from magnetic fluxes passing through the drive coil at the other three corners, or magnetic fluxes passing through the drive coil at two corners adjacent to each other of the four corners of the lens drive device are different from magnetic fluxes passing through the drive coil at the other two corners.

摘要： An optical device may include a movable body holding a lens, a fixed body movably holding the movable body, a drive magnet and a drive coil for relatively moving the movable body with respect to the fixed body, and a metal member fixed to the drive magnet. The drive magnet is fixed to one of the movable body and the fixed body and the drive coil is fixed to the other of the movable body and the fixed body. A nickel plating layer containing at least nickel is formed on a surface of the drive magnet and a surface of the metal member, and the drive magnet and the metal member are joined to each other by a joining layer which is made of tin-based metal containing at least tin and is disposed between the drive magnet and the metal member.
