Title:
LENS DRIVER AND CAMERA MODULE
Document Type and Number:
Japanese Patent JP2019082641
Kind Code:
A
Abstract:
To provide a lens driver with which it is possible to more reliably electrically connect a wire rod and a leaf spring together.SOLUTION: The lens driver moves a lens holding member 2 held by a leaf spring 6 by generating a force with a current flowing in a coil 3 and a magnetic field generated by a magnet along the direction of the optical axis of a lens body. The coil 3 includes a wound part held to the lens holding member 2 and an extending part 33A linked to the wound part. The lens holding member 2 includes a holding part 72A around which a wire rod constituting the extending part 33A is wound, a pier part 82 enclosing a storage part that is a space in which a conductive adhesive for bonding a wire rod portion to the leaf spring 6 is arranged, and one or a plurality of stopper parts SP for restricting the movement of the leaf spring 6 toward the pier part 82 side. The stopper part SP projects closer to the leaf spring 6 side than a first warped part WP that is the start point of wire rod winding in the holding part 72A.SELECTED DRAWING: Figure 20
