Abstract
The present invention aims to provide a lens driving device capable of realizing the reduction of power consumption by improving the driving efficiency of an electromagnetic drive mechanism. The lens driving device includes: one or mores drive coils having one or more forward path sides and one or more return path sides, and drive magnets each having a forward path side magnet plate and a return path side magnet plate. The magnetization directions of the forward path side magnet plate and the return path side magnet plate of each drive magnets define an angle which is expanded towards the oppositely arranged one or more drive coils. The magnetic induction intensity applied to the drive coils from the drive magnets can be increased and improved, and thus powerful lorentz force can be effectively generated by the drive coils after being electrified.
