SOUNDPROOF STRUCTURE AND METHOD FOR MANUFACTURING SOUNDPROOF STRUCTURE
A soundproof structure includes a porous fibrous body that attenuates incident sound waves, wherein the fibrous body is formed of fibers having an average fiber diameter of 0.5 µm or more and 5 µm or less, and includes a surface layer on which the sound waves are incident and a propagation layer that is stacked with the surface layer and that propagates the sound waves from the surface layer, and wherein the propagation layer includes a high density layer having a density higher than a density of the surface layer.
