PROBLEM TO BE SOLVED: To provide a sound insulation structure which can inhibit noise from entering into a vehicle cabin through a first opening formed at a panel partitioning the vehicle cabin interior from the vehicle cabin exterior.SOLUTION: A sound insulation structure 7 includes: a plate-like member 71 having an opening 71a; a first elastic member 72 which is disposed at the lower surface side of the plate-like member 71 and formed so as to cover the opening 71a; and a second elastic member 73 which is disposed at the upper surface side of the plate-like member 71 and formed so as to cover the opening 71a. Through holes 71b are formed around the opening 71a in the plate-like member 71. Projection parts 72a which are inserted into the through holes 71b are formed at the first elastic member 72. Through holes 73a into which the projection parts 72a are inserted are formed at the second elastic member 73. An engagement part 72b, which engages with the second elastic member 73 in a state where the projection parts 72a are inserted into the through holes 71b and 73a, is formed at each projection part 72a.SELECTED DRAWING: Figure 6
