Example embodiments include a driving device having: a plurality of vibrating members that may vibrate when the vibrating members are driven; and a holding part that may hold the vibrating members. The holding part may include a first member with which one or more of the vibrating members may be brought into contact, and a second member with which one or more of the vibrating members may be brought into contact. The first member and the second member may be partially coupled to each other. A grounding member for electrically grounding a member held by the holding part may be brought into contact with one of the first member and the second member that is more difficult to vibrate.
