Zusammenfassung:	To provide a means capable of suppressing deterioration in the soundproofing performance of a soundproofing material capable of exhibiting high soundproofing performance over a wide range of a frequency range of 2000 Hz or less.A soundproofing material including a sheet having elasticity, and a support portion partitioning the sheet into a partition portion while supporting the sheet is configured so that a surface rigidity (k) of the sheet and a surface density (m) of the sheet in the partition portion satisfy a relationship of the following Expression 1. Further, the soundproofing material is disposed on a substrate and a vibration separation layer is further disposed between the soundproofing material and the substrate to configure a soundproofing structure:12⁢π⁢km>900[Hz].[Expression⁢1]
