SOUNDPROOFING STRUCTURE
The present invention addresses the problem of providing a soundproofing structure with which it is possible to obtain high soundproofing performance and to suitably maintain formation properties. Provided is a soundproofing structure comprising a micro-perforated sheet having a plurality of through-holes that pass through in the thickness direction, wherein: in a main surface of the micro-perforated sheet, the average opening diameter of the through-holes is at least 0.1 mum and less than 100 mum; at least some of the plurality of through-holes are through-holes A shaped so as to have the greatest pore diameter in the interior thereof; and in the through-holes A, 1 < phi2/phi1 <= 5, where phi1 is the smallest pore diameter and phi2 is the greatest pore diameter.
课题在于提供一种可获得高隔音性能且能够适当地保持形成材料的特性的隔音结构体。本发明的隔音结构体具备具有沿厚度方向贯穿的多个贯穿孔的微细穿孔板，其中，微细穿孔板的主表面上的贯穿孔的平均开口直径为0.1μm以上且小于100μm，多个贯穿孔的至少一部分为在内部成为最大孔径的形状的贯穿孔A，在贯穿孔A中，若将最小孔径设为且将最大孔径设为则为
