SOUNDPROOFING STRUCTURE
Provided is a soundproof structure that can obtain high soundproofing performance and suitably maintain characteristics of a forming material. A soundproof structure includes: a microperforated sheet having a plurality of through-holes penetrating in a thickness direction, in which an average opening diameter of the through-holes in a main surface of the microperforated sheet is 0.1 µm or more and less than 100 µm, at least some of the plurality of through-holes are a through-hole A that has a shape having an internal maximum hole diameter, and in the through-hole A, assuming that a minimum hole diameter is φ1and a maximum hole diameter is φ2, 1 < φ2/φ1≤ 5 is satisfied.
