PROBLEM TO BE SOLVED: To contribute to miniaturization by decreasing the layout space of a drive coil and a drive magnet in a lens drive using a linear actuator. SOLUTION: The lens drive is provided with a driven body 1 attaching a lens, a guide shaft for movably guiding the driven body 1 in the direction of a lens optical axis, the drive coil 7 wound flatly and attached to the driven body 1, and the drive magnet 4 opposed to the drive coil 7 and laid out along the moving direction of the driven body 1. The drive coil 7 and the drive magnet 4 are provided to be matched on an outer peripheral shape of the lens. COPYRIGHT: (C)2004,JPO&NCIPI
