Abstract
A lens driving device being capable of securing smooth movement of a lens support body includes a guide mechanism. The guide mechanism includes a guide groove and a guide projection for fitting into the guide groove so as to be able to slide. The guide groove includes a bottom face formed in a planar shape. In an XYZ orthogonal coordinate system wherein a sliding direction is an X direction and a height direction is a Z direction, the guide projection includes a Z direction end face opposing the guide groove bottom face. A cross-section profile of the Z direction end face sectioned along an XZ plane is formed with a curved shape convex on the guide groove bottom face side, and a cross-section profile of the Z direction end face sectioned along a YZ plane is formed with a curved shape convex on the guide groove bottom face side.
