Abstract

The present invention addresses the problem of providing a sound insulating structure which provides a sufficient sound insulating effect even when an adhesive layer is arranged therein, and in which a shift in the frequency band where the sound insulating effect is generated is unlikely to occur. This sound insulating structure includes, at least: a sound insulating member that includes a sheet-like sheet section and plural projections arranged on the sheet section; and an adhesive layer arranged on a surface of the sheet section on the opposite side of the side provided with the projections, and the sound insulating structure satisfies the following Formula (1): E_glue/I_glue>0.5×(E_membrane/H) (1) (wherein, E_glue (MPa): storage modulus of adhesive layer, I_glue (mm): average thickness of adhesive layer, E_membrane (MPa): storage modulus of sheet section and projections, and H (mm): average height of sheet section and projections).
