To provide a sound-absorbing material that exhibits sound-absorbing property excellent in a low frequency region, and is also excellent in space-saving performance. The laminated sound-absorbing material contains a plurality of fiber layers, and a base material layer existing between the fiber layer and the fiber layer, in which the laminated sound-absorbing material contains at least three fiber layers, each fiber layer is formed of fibers having a fiber diameter of less than 450 nanometers, and has a basis weight of 0.1 to 50 g/m2, and the base material layer has a basis weight of 1 g/m2 or more and a thickness of 0.1 millimeter or more, and the base material layer is at least one selected from the group of a nonwoven fabric, a film, a glass fiber and paper.
