Abstract
A lens drive device may include a front side spring member which is connected between a movable body having a lens and a support body. The front side spring member includes a support body side connecting part, a movable body side connecting part and a arm part connected between the support body side connecting part and the movable body side connecting part. The support body includes a yoke having a yoke front plate part and the yoke front plate part is formed with a yoke opening part which is overlapped with at least a part of the front side spring member. Damper material having viscoelasticity is provided, for example, on a portion extending over the movable body side connecting part and the arm part and overlapped with the yoke opening part in the lens optical axis direction. Therefore, the damper material can be applied to the front side spring member through the yoke opening part in the final stage of assembling steps.
