Abstract
A lens holder driving apparatus includes: an auto-focusing lens holder driving section (AF section) including a permanent magnet; and a camera-shake correcting section that corrects camera-shake by moving the AF section with respect to a fixed section. The camera-shake correcting section includes: a supporting member that supports the AF section in a rocking manner; and a camera-shake correction coil disposed on the fixed section. The fixed section includes: a coil substrate having an inner peripheral side wall defiling a circular opening; a flexible printed-circuit board (FPC) disposed at a lower part of the coil substrate, a base that faces the FPC, and a dust generation prevention member that covers at least the inner peripheral side wall and that prevents generation of dust due to the inner peripheral side wall being scraped.
