1. A lens drive device comprising:
a base member;
a lens frame positioned on an upper side of the base member, a lens is attached to the lens frame;
an actuator extending along an optical axis direction of the lens at an outer periphery of the lens frame, and being capable of extending and contracting in the optical axis direction of the lens, one end portion of the actuator in the optical axis direction being fixed to the base member;
a leaf spring member extending along the outer periphery of the lens frame, and including a first end portion and a second end portion, the first end portion frictionally engaging an outer periphery of the other end portion of the actuator in the optical axis direction such that the other end portion is biased toward the lens frame, and the second end portion gripped by the lens frame on a first surface close to an optical axis of the second end portion and a second surface opposite to the first surface; and
a support point portion positioned closer to the first end portion than a fixed portion, the second end portion of the leaf spring member and the lens frame are fixed at the fixed portion, the second surface of the second end portion and the lens frame contact each other at the support point portion as a support point of the leaf spring member.
