Lens driving device, camera module, and camera-mounted device

A lens driving device, comprising:

• an auto-focusing driving part including:
• an auto-focusing coil part to be disposed at a periphery of a lens part;
• an auto-focusing magnet part to be disposed to be radially spaced apart from the auto-focusing coil part;
• and
• an auto-focusing supporting part configured to support an autofocus movable part to be movable in an optical-axis direction with respect to an autofocus fixing part, the autofocus movable part including the auto-focusing coil part, the autofocus fixing part including the auto-focusing magnet part, and the auto-focusing driving part being configured to perform automatic focusing by utilizing a driving force of a voice coil motor composed of the auto-focusing coil part and the auto-focusing magnet part;
• and
• a shake-correcting driving part including:
• a shake-correcting magnet part to be disposed in the autofocus fixing part;
• a shake-correcting coil part to be disposed to be spaced apart from the shake-correcting magnet part in the optical-axis direction;
• and
• a shake-correcting supporting part configured to support a shake-correcting movable part to be able to sway in an optical-axis-orthogonal plane with respect to a shake-correcting fixing part, the shake-correcting movable part including the shake-correcting magnet part and the auto-focusing driving part, the shake-correcting fixing part including the shake-correcting coil part, and the shake-correcting driving part being configured to perform shake correction by utilizing a driving force of an another voice coil motor composed of the shake-correcting coil part and the shake-correcting magnet part, wherein:
• the shake-correcting fixing part includes:
• a coil board consisting of a multilayer printed wiring board in which a plurality of unit layers consisting of a conductor layer and an insulating layer are stacked on one another, and
• a base on which the coil board is to be placed, and
• the shake-correcting coil part, an external terminal, and a conductor pattern including a power-supply line configured to connect the external terminal to the shake-correcting coil part are integrally formed in the coil board.
