To provide soundproofing means which offers superior soundproofing performance and reduced manufacturing cost.SOLUTION: The above challenge is cleared by a sheet-like soundproof structure comprising an elastic sheet, and a support member provided with multiple openings partitioned by a frame and configured to support the sheet and divide the sheet into planer divided sections. A surface of the support member on a side with the sheet has asperities, and the sheet is placed on the surface of the support member such that protrusions of the asperities penetrate in a thickness direction of the sheet.SELECTED DRAWING: Figure 2
【課題】優れた防音性能を有するとともに、製造コストの低減を実現することが可能な防音手段を提供する。【解決手段】弾性を有するシートと、桟部により区画された複数の開口部を有し、かつ、前記シートを支持するとともに前記シートを面状の区画部に区画する支持部材とを備え、前記支持部材の前記シートが配置された側の表面が凹凸を有し、前記凹凸の凸部が前記シートの厚さ方向に貫入するように前記シートが前記支持部材の前記表面に配置されている、シート状防音構造体により、上記課題は解決される。【選択図】図2
