To suppress unstable three-dimensional variations even though a controllable range of vibrations is expanded and a vibration transmission material is arranged on the vertically upper side from an object to be damped.

A vibration damping device 50 consists of a curved rope member 13, a first base body 1 containing a first fixed part 2 fixed to a vibration transmission member, and a second base body 21 containing a second fixed part 22 fixed to an object to be damped. The second fixed part 22 is situated on a vertically lower side from the first fixed part 2. The first base body 1 and second base body 21 have a first inner fixing part 5 and a second inner fixing part 25, respectively. The curved rope member 13 is fixed to the first inner fixing part 5 and second inner fixing part 25.
