Problems solved by technology

[0002] Voice coil motor (VCM) technology used in existing general camera modules is difficult to apply to miniature low-power camera modules, and research related to this has been actively conducted
[0003] In the case where the camera module is configured to be mounted in a small electronic product such as a smartphone, the camera module may often be subjected to shocks while in use, and may perform weak shaking due to shaking of the user's hand, for example.

Abstract

An embodiment comprises: a housing; a bobbin disposed in the housing; a first coil disposed on the bobbin; a magnet disposed at the housing; an elastic part coupled to the bobbin and the housing; a circuit board disposed under the housing and comprising a pad part; a base disposed under the circuit board; a terminal disposed on the base; and a support part, one end of which is coupled to the elastic part and the other end of which is coupled to the terminal, wherein the pad part comprises: a first pad disposed beneath the circuit board; a second pad on the circuit board; and a third pad connecting the first pad and the second pad.

Description

technical field [0001] Embodiments relate to a lens moving device, and a camera module and an optical device respectively including the lens moving device. Background technique [0002] A Voice Coil Motor (VCM) technology used in an existing general camera module is difficult to apply to a miniature low-power camera module, and research related thereto has been actively conducted. [0003] In a case where the camera module is configured to be mounted in a small electronic product such as a smartphone, the camera module may often be subjected to shocks while in use, and may be slightly shaken due to shaking of a user's hand, for example. In consideration of this, a technology that enables a device for preventing hand shake to be additionally mounted to a camera module is being developed. Contents of the invention [0004] technical problem [0005] Embodiments provide a lens moving device capable of improving ease of soldering a circuit board to a terminal and preventing ...
