Abstract:
A lens driving device includes a movable part, a plate spring that movably supports the movable part, a coil provided on the movable part, and magnets facing the coil. An outer portion of the movable part includes protrusion opposing parts where first restricting protrusion and second restricting protrusions face each other in an optical axis direction and non-opposing parts where the first restricting protrusion and the second restricting protrusions do not face each other in the optical axis direction, the coil is formed by winding a conductor wire around the outer portion in a circumferential direction and includes first coil portions positioned in the protrusion opposing parts and second coil portions positioned in at least some of the non-opposing parts, and the width of the second coil portions in the optical axis direction is greater than the width of the first coil portions in the optical axis direction.
