SOUNDPROOFING STRUCTURE, PARTITION STRUCTURE, WINDOW MEMBER, AND CAGE
Provided is a soundproofing structure including: a plate-like member which has a plurality of through-holes passing therethrough in a thickness direction, in which in a case where an average opening diameter of the through-holes is 0.1 µm or greater and less than 100 µm, and in a case where the average opening diameter of the through-holes is set as phi (µm) and a thickness of the plate-like member is set as t (µm), an average opening ratio rho of the through-holes is greater than 0 and less than 1 and falls in a range where a center is rho_center = (2 + 0.25 × t) × phi -1.6 , a lower limit is rho_center - (0.052 × (phi/30) -2 ), and an upper limit is rho_center + (0.795 × (phi/30) -2 ).
