To provide a sound insulating member and a method for manufacturing the sound insulating member.SOLUTION: There is provided a molded body (sound insulation member 1) made of liquid crystal polyester as a forming material, which includes a core layer 11 formed in an inner layer of the molded body and an alignment layer 12 formed on the surface of the molded body. The liquid crystal polyester forming the alignment layer 12 is more oriented than the liquid crystal polyester forming the core layer 11, and ratio of elastic modulus of the core layer 11 to elastic modulus of the molded body 1 is 0.60 or more and 0.95 or less.SELECTED DRAWING: Figure 2
【課題】遮音部材及び遮音部材の製造方法を提供する。【解決手段】液晶ポリエステルを形成材料とする成形体(遮音部材1)であり、成形体の内層に形成されるコア層11と、成形体の表面に形成される配向層12と、を有する。配向層12を形成する液晶ポリエステルは、コア層11を形成する液晶ポリエステルよりも配向しており、成形体1の弾性率に対するコア層11の弾性率の比が0.60以上0.95以下である。【選択図】図2
