PROBLEM TO BE SOLVED: To provide a sound insulation material excellent in sound insulation performance, and a wire harness having a sound insulation material.SOLUTION: A sound insulation material is composed of a nonwoven fabric laminate including a plurality of laminated nonwoven fabric layers. The nonwoven fabric has a skin nonwoven fabric and a substrate nonwoven fabric having a basis weight larger than that of the skin nonwoven fabric. At least the substrate nonwoven fabric has a first substrate nonwoven fabric 31 and a second substrate nonwoven fabric 32. The skin nonwoven fabric 2 is disposed between the first substrate nonwoven fabric 31 and the second substrate nonwoven fabric 32 so as to compose a sound insulation material 1. The sound insulation material 1 is integrated with a wire harness 7 so as to compose a wire harness 6 having a sound insulation material.

    【課題】遮音性能の優れた遮音材及び遮音材付きワイヤーハーネスを提供する。【解決手段】複数の不織布が積層された不織布積層体から構成される遮音材であって、前記不織布が表皮材不織布と該表皮材不織布よりも目付の大きい基材不織布とを有し、少なくとも、前記基材不織布が第一基材不織布31と第二基材不織布32を有し、前記表皮材不織布2を前記第一基材不織布31と前記第二基材不織布32の間に配置して遮音材1を構成し、該遮音材1をワイヤーハーネス7と一体化して遮音材付きワイヤーハーネス6を構成した。【選択図】図1
