To provide a sound insulation structure in which an internal pressure set during pressurizing can be kept for a long time even if the sound insulation structure is not connected to a driving device having a pump and the like for controlling the internal pressure.SOLUTION: A sound insulation structure 1 formed in a panel shape includes; a bag body part 2 which is formed by a thin film material and is filled with gas inside; a first rigid material 31 of a planar material, which has a plurality of openings that are brought into close contact with a first face being a side of the bag body part; a second rigid material 32 of a planar material, which has a plurality of openings that are brought into close contact with a second face of the bag body part being a side of an opposite side; a frame body part 4 which maintains the first rigid material, the bag body part and the second rigid material in a laminated state; and elastic materials (61, 62) interposed between the first rigid material and the bag body part and between the second rigid material and the bag body part. The elastic materials are arranged along an inner peripheral edge 43 of the frame body part.SELECTED DRAWING: Figure 1 【課題】内圧を制御するためのポンプなどを備えた駆動装置に接続しなくても、加圧時に設定した内圧を長期間、保持することが可能な遮音構造体を提供する。【解決手段】パネル状に形成される遮音構造体１である。そして、薄膜材によって形成されて内部に気体が封入された袋体部２と、袋体部の側面となる第１面に密着させた複数の開口を有する面状材の第１剛性材３１と、反対側の側面となる袋体部の第２面に密着させた複数の開口を有する面状材の第２剛性材３２と、第１剛性材と袋体部と第２剛性材とを積層させた状態で保持させる枠体部４と、第１剛性材と袋体部との間及び前記第２剛性材と袋体部との間に介在させる弾性材（６１，６２）とを備えている。この弾性材は、枠体部の内周縁４３に沿って配置されている。【選択図】図１
