This sound insulating structure (1) is provided with: a panel (2); a sound insulating material (3) laminated to the panel (2); a reinforcing material (4) provided between the panel (2) and the sound insulating material (3) and bonded to the panel (2); and an air layer (S) formed between the panel (2) and the reinforcing material (4). The reinforcing material (4) has a plurality of through-holes (5). As a result, it is possible to suppress an increase in overall weight and to secure sound shielding properties and sound insulating properties.
