The present invention provides a sound insulation member capable of appropriately enlarging the surface area of a sound insulation surface, and a method for manufacturing the sound insulation member. The sound insulation member (10) is provided with a planar sound insulation material (11). The sound-insulating material (11) has a sound-insulating surface having a folded pattern (LP) in which a bellows structure overlaps on two mutually orthogonal axes in an in-plane direction in which the sound-insulating material (11) is viewed in a plane-perpendicular view angle. By providing such a folding pattern (LP) on the sound-insulating member (10), a wide surface area of the sound-insulating surface can be ensured compared to a structure in which a bellows structure is repeated only in one direction.
本发明提供一种能够适当地扩大隔音面的表面积的隔音部件及其制造方法。隔音部件(10)具备面状的隔音材料(11)。隔音材料(11)具有隔音面,该隔音面具有在以面垂直视角观察隔音材料(11)的面内方向上蛇腹结构在相互正交的两个轴上重复的折叠图案(LP)。通过在隔音部件(10)设置这样的折叠图案(LP),与蛇腹结构仅在一个方向上重复的结构相比,能够宽阔地确保隔音面的表面积。
