Zusammenfassung:	To provide a means capable of exhibiting high soundproofing performance over a wide range of a frequency range of 2000 Hz or less. A soundproofing material includes a sheet having elasticity and a support portion partitioning the sheet into partition portions while holding the sheet, in which a surface rigidity (k) and a surface density (m) of the sheet in the partition portion are configured to satisfy a relationship of the following Expression 1. (see above formula) Le problème décrit par la présente invention est de fournir un moyen capable de présenter des performances d'insonorisation élevées sur une large plage de fréquences de 2000 Hz ou moins. La solution selon l'invention porte sur un matériau d'insonorisation comprenant une feuille élastique et une partie de support qui maintient la feuille et qui sépare la feuille en sections séparées, la rigidité (k) de la feuille et la densité de surface (m) de la feuille dans les sections partitionnées satisfont la relation d'une équation 1.
