Abstract
To provide a lens driving apparatus that drives a lens in its optical axis-direction without inclining it, and a lens driving apparatus that drives a bobbin in the optical axis-direction smoothly without increasing the frictional force between a ball arranged between the bobbin and a cover, and the bobbin and cover while maintaining high driving power. The lens driving apparatus comprises the polygonal cylindrical bobbin that houses the lens, the box-shaped cover that receives the bobbin, a drive unit that moves the bobbin in the optical axis-direction of the lens, and a support unit that supports the bobbin.
