Document Type and Number:
WIPO Patent Application WO/2018/198796
Kind Code:
A1
Abstract:
[Problem] To provide: a lens drive device with which a leaf spring can be mounted on a support base while retaining a high degree of flatness and the perpendicularity of the optical axis of a lens holding material supported by the leaf spring can be maintained; a camera module using the lens drive device; and a method for manufacturing the lens drive device. [Solution] An attachment portion 21a, which is a fixing-side support portion of a lower leaf spring 20A, is placed on a spring fixing surface 41A formed on a support base 40, a conductive plate 50A with a connection terminal 52 is stacked on the attachment portion 21a, and the attachment portion 21a and the conductive plate 50A are calked around a positioning projection 42a projecting from the spring fixing surface 41A. Since the fixing-side support portion of the lower leaf spring 20A is received by the spring fixing surface 41A, the flatness of the lower leaf spring 20A can be maintained.
