Abstract:
A lens drive device includes a movable portion, a fixed portion, and a nonmagnetic case. The movable portion includes a double-pole magnet having two pairs of magnetic poles, a first coil opposing to the double-pole magnet in a perpendicular direction to a light axis, and a lens holder being movable to the double-pole magnet in a direction of the light axis. The fixed portion includes a second coil arranged so as to oppose to the double-pole magnet in the direction of the light axis. The nonmagnetic case is attached to the fixed portion so as to cover the movable portion. The double-pole magnet includes a first section and a second section. L 1 /L 2  is 1.1 to 2.0, where L 1  and L 2  are respectively a length of the first and second sections in the direction of the light axis.

Claim (Index 3):
The lens drive device according to  claim 2 , wherein\n the yoke covers the whole of a first outer side surface in the first section of the outer side surface and covers a part of a second outer side surface in the second section of the outer side surface, and a distance between the yoke and the fixed portion is larger than a distance between the double-pole magnet and the fixed portion.
