[Problem] Provided is a vibration damping structure that can obtain a high vibration damping effect without reducing rigidity of a structure itself.[Means for Solution] A vibration damping structure 1 includes a panel 10 which is a structure and a damping member 11 joined to the panel 10. The damping member 11 has a plurality of joined portions 11b joined to a mating surface 10a of the panel 10 through respective joined surfaces 11d in the X direction, and a plurality of spacing portions 11a recessed toward the side opposite to the panel 10 in the Z direction between adjacent joined portions 11b. The damping member 11 is formed such that the damping member 11 is higher in damping than the panel 10 and a resonance frequency of the damping member 11 is formed such that it is substantially the same as a primary resonance frequency of the panel 10.
