There is provided a vibration suppression device of a rope-like body that can use a negative restoring force that amplifies a displacement of a rope-like body of an elevator to prevent the displacement from becoming unstable. A vibration suppression device (21) includes a first displacement measurement unit, a first displacement amplifier, and a control unit (24). The first displacement measurement unit measures a displacement in a lateral direction of the rope-like body due to vibration about an equilibrium position (20) at a first position (P1) in a longitudinal direction of the rope-like body. The first displacement amplifier applies, to the rope-like body, a negative restoring force that amplifies the displacement of the rope-like body. The control unit (24) causes the first displacement amplifier to apply a negative restoring force smaller than a positive restoring force, based on the displacement measured by the first displacement measurement unit.
