Abstract: The present invention provides a lens drive apparatus including: an image pickup lens group; a lens frame holding the image pickup lens group; an actuator comprising a magnet, a yoke, and a coil formed of an electric conductor; a casing housing the lense frame and the actuator therein; and at least one guide shaft parallel to an optical axis of the image pickup lens group. An electromagnetic force generated when electricity is applied to the coil, moves the lens frame and the image pickup lens along the optical axis.
