An object of the present invention is to provide a sound-insulating structural body with which a high sound insulation effect can be obtained even when an uneven structural body having an uneven structure is disposed on a member having a high rigidity. Provided is a sound-insulating structural body including: a flexible member in which a load giving a deformation rate of 4% in a compression test performed by a compression tester is 160 kPa or less; an adherend on which the flexible member is disposed; and an uneven sheet member having an uneven structure that includes a sheet section and protruding parts provided on a surface of the sheet section. In this sound-insulating structural body, the flexible member is provided such that it is arranged between the adherend and the uneven sheet member.
