LENS DRIVE DEVICE, CAMERA MODULE USING SAID LENS DRIVE DEVICE, AND METHOD FOR MANUFACTURING LENS DRIVE DEVICE

摘要

[Problem] Provided are: a lens drive device wherein the elastic force of an upper sheet spring and a lower sheet spring can be set appropriately, the upper and lower sheet springs supporting a lens holding member; a camera module using the lens drive device; and a method for manufacturing the lens drive device. [Solution] A lens holding member 10 on which a coil 60 is mounted is supported by an upper sheet spring 30 and a lower sheet spring 20A, 20B, and in an initial state in which the coil 60 is not electrically energized, the lens holding member 10 is in contact with a support base 40. The upper affixed-side support section of the upper sheet spring 30 is affixed to a support member 50 disposed inside the ceiling section of a case 3. A biasing force for biasing the lens holding member 10 toward the support base 40 is smaller on the lower sheet spring 20A, 20B side than on the upper sheet spring 30 side.
