To increase transmission loss of travel noise by extracting sound reduction function from a core material.SOLUTION: A vehicle panel structure includes a double wall panel 5 in which a core material 51a having at least a predetermined thickness across the whole in-plane directions of an outer wall 21 and an inner wall 22 is encapsulated between the walls 21, 22 opposite to each other, where a core layer 50 is formed by being filled with the core material 51a made of a fiber material or gas permeable foam material and the outer wall 21 has a stiffness that is lower than a stiffness of the inner wall 22.SELECTED DRAWING: Figure 1

    【課題】コア材による音の減衰機能を引出して走行音の透過損失を向上させること。【解決手段】対向する外壁21と内壁22との間に、これら壁21,22の面内方向全体に渡って少なくとも所定の厚みを有するコア材51aが封入された二重壁パネル5からなり、コア層50は、繊維材又は通気性を有するフォーム材から成るコア材51aが充填して形成されたものであり、外壁21の剛性を内壁22の剛性に比して下げる構成とした。【選択図】図1
