Abstract
A lens drive apparatus includes a damper compound that is disposed between at least one protrusion and a fixed member and that suppresses undesired resonance of an auto-focusing lens driving section in a direction of an optical axis. The at least one protrusion protrudes from a magnet holder in the direction of the optical axis toward the fixed member and is inserted into at least one hole of a leaf spring provided to the auto-focusing lens driving section.
