A lens holder driving apparatus comprising: an auto-focusing lens holder driving section that moves, along an optical axis, a lens holder holding a lens barrel, the auto-focusing lens holder driving section including a permanent magnet; and a camera-shake correcting section that corrects camera-shake by moving the auto-focusing lens holder driving section in a first direction and a second direction with respect to a fixed section, the first direction and the second direction being orthogonal to the optical axis and orthogonal to each other, wherein the camera-shake correcting section comprises: a supporting member that supports the auto-focusing lens holder driving section with respect to the fixed section to allow the auto-focusing lens holder driving section to rock in the first direction and the second direction; and a camera-shake correction coil disposed on the fixed section to face the permanent magnet, the fixed section comprises: a coil substrate on which the camera-shake correction coil is formed, the coil substrate having an inner peripheral side wall defining a circular opening, a flexible printed-circuit board disposed at a lower part of the coil substrate, a base that faces the flexible printed-circuit board, and a dust generation prevention member (47, 48) that covers at least the inner peripheral side wall of the coil substrate and that prevents generation of dust due to the inner peripheral side wall of the coil substrate being scraped, the dust generation prevention member being a member different from the base, the dust generation prevention member is composed of a collision avoidance member preventing collision between the inner peripheral side wall of the coil substrate and the lens barrel, and the collision avoidance member is composed of a ring-shaped cylindrical portion (474, 484) covering the inner peripheral side wall of the coil substrate. an auto-focusing lens holder driving section that moves, along an optical axis, a lens holder holding a lens barrel, the auto-focusing lens holder driving section including a permanent magnet; and a camera-shake correcting section that corrects camera-shake by moving the auto-focusing lens holder driving section in a first direction and a second direction with respect to a fixed section, the first direction and the second direction being orthogonal to the optical axis and orthogonal to each other, wherein the camera-shake correcting section comprises: a supporting member that supports the auto-focusing lens holder driving section with respect to the fixed section to allow the auto-focusing lens holder driving section to rock in the first direction and the second direction; and a camera-shake correction coil disposed on the fixed section to face the permanent magnet, a supporting member that supports the auto-focusing lens holder driving section with respect to the fixed section to allow the auto-focusing lens holder driving section to rock in the first direction and the second direction; and a camera-shake correction coil disposed on the fixed section to face the permanent magnet, the fixed section comprises: a coil substrate on which the camera-shake correction coil is formed, the coil substrate having an inner peripheral side wall defining a circular opening, a flexible printed-circuit board disposed at a lower part of the coil substrate, a base that faces the flexible printed-circuit board, and a dust generation prevention member (47, 48) that covers at least the inner peripheral side wall of the coil substrate and that prevents generation of dust due to the inner peripheral side wall of the coil substrate being scraped, the dust generation prevention member being a member different from the base, a coil substrate on which the camera-shake correction coil is formed, the coil substrate having an inner peripheral side wall defining a circular opening, a flexible printed-circuit board disposed at a lower part of the coil substrate, a base that faces the flexible printed-circuit board, and a dust generation prevention member (47, 48) that covers at least the inner peripheral side wall of the coil substrate and that prevents generation of dust due to the inner peripheral side wall of the coil substrate being scraped, the dust generation prevention member being a member different from the base, the dust generation prevention member is composed of a collision avoidance member preventing collision between the inner peripheral side wall of the coil substrate and the lens barrel, and the collision avoidance member is composed of a ring-shaped cylindrical portion (474, 484) covering the inner peripheral side wall of the coil substrate.
