Abstract
A structural body including a plurality of convex-shaped rubber-elastic resonant portions, and a sheet-like support that supports the resonant portions. A specific gravity of the resonant portions is 1.0 g/cmor more and 3.0 g/cmor less, a height of the resonant portions is from 50 μm to 100 mm, and an areal density of the support is 1.0 kg/mor less.
