A vibration damping device for a vibration damping target has a linear member that includes a plurality of wires, which are held so that each of the plurality of wires is relatively displaced in a state that the wires are in contact with one another, and a cover member that covers a peripheries of the plurality of the wires, wherein the plurality of the wires and part of the cover member are fixed to the vibration damping target, and a region of the linear member that flexes through plastic deformation of the linear member is located near each point where the linear member is fixed to the vibration damping target.
