A method for producing a vibration damping structure body includes: a first step of providing a first resin on a surface of a panel member; a second step of curing a surface of the first resin by heating; a third step of providing a second resin to be a restriction layer on the surface of the first resin; and a fourth step of heating the first resin and the second resin thereby curing the second resin to form the restriction layer and causing the first resin to foam internally to form the vibration damper.

A vibration damping structure includes a panel member, a vibration damper, and a restriction layer. The vibration damper has a plurality of protruding parts each extending continuously along a first direction being a direction in which the vibration damper is to be stretched or compressed in response to application of a bending load to the panel member, and spaced away from each other in a second direction orthogonal to the first direction, and a plurality of recessed parts each formed between two protruding parts adjacent to each other among the protruding parts. The restriction layer fits in the recessed parts.
