る前記防音材。[Claims for Utility Model Registration] Sound absorbing material layer 1 and sound insulating sheet material layer 2 laminated on its surface
A sound insulating material 3 having a hole 11 formed in the sound absorbing material layer 1 and a through hole 21 formed in the sound insulating sheet material layer 2, thereby forming a through hole 7 through which another member 4 passes. In, the sound insulating sheet material layer 2 in a state where the other member 4 is not fitted
The through hole 21 is substantially concentric with the fitting member 4a of the other member 4 when the other member 4 is fitted into the through hole 21, and is smaller than the cross section of the fitting portion 4a, and has a shape of the cross section. The sound insulating sheet material layer around the through hole 21 has a plurality of concave or convex slacks 22 extending radially around the through hole 21. The soundproofing material.
