Patent ID: 8078043

Claim:
A lens barrel comprising: a lens holding member; a fixing member configured to perform a positioning of the lens holding member in an optical axis direction; a driving member including a coil fixed on the lens holding member and a magnet fixed on the fixing member; and a guide bar configured to guide the lens holding member which is driven by an electromagnetic force acting between the coil and the magnet in a plane orthogonal to the optical axis, wherein each of the coil and the magnet is a plate member whose longitudinal is in the optical axis direction, the coil is disposed so as to be overlapped with the magnet when viewed in a direction orthogonal to the optical axis, the guide bar is disposed so as to be overlapped with both of the coil and the magnet when viewed in the optical axis direction, and the lens barrel includes a flexible printed circuit configured to supply current to the coil fixed on the lens holding member, the flexible printed circuit being disposed so as to be overlapped with the both of the coil and the magnet when viewed in the optical axis direction.
