A driving mechanism is provided and drives an optical element. The driving mechanism includes a holding unit, a base unit, an elastic element, and a driving assembly. The holding unit holds an opticalelement. The base includes a body and a connecting component. The connecting component is formed in the body by insert molding, and has a first contact and a second contact. The first contact and thesecond contact are located on different sides of the base, and the first contact is electrically connected to a base unit outside the driving mechanism. The elastic element connects the holding unitto the base, and the second contact is electrically connected to the elastic elements. The driving mechanism drives the optical element to move relative to the base.
