    摘要： 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 ).

    摘要： An object is to provide a soundproofing structure, a partition structure, a window member, and a cage which exhibit high soundproofing performance in a broad frequency band, can be miniaturized, can ensure ventilation properties, and have a light transmittance. Provided is a soundproofing structure including: a plate-like member which has a plurality of through-holes passing therethrough in a thickness direction; and a frame member which includes an opening portion, in which membrane vibration of the plate-like member is enabled by fixing the plate-like member to a peripheral edge of the opening portion of the frame member, an average opening diameter of the through-holes is in a range of 0.1 µm to 250 µm, and a first unique vibration frequency of the membrane vibration of the plate-like member is present in a range of 10 Hz to 100000 Hz.

    摘要： An object of the present invention is to provide an aluminum plate which is excellent in terms of both step suitability and working characteristics and a collector for a storage device using the same. The aluminum plate of the present invention is an aluminum plate having a plurality of through-holes formed in a thickness direction, in which a thickness of the aluminum plate is 40 µm or less, an average opening diameter of the through-holes is 0.1 to 100 µm, an average opening ratio by the through-holes is 2% to 30%, a content of Fe is 0.03% by mass or more, and a ratio of the content of Fe to a content of Si is 1.0 or more.
