To provide a vehicular roof panel which suppresses the plastic deformation of a roof panel design surface when heating for baking finish, etc., of a vehicle without decreasing the degree of freedom for design property and which can suppress the external quality failure.SOLUTION: A vehicular roof panel 1A that is joined to a vehicle upper part structure member BS formed of a first material includes: a roof panel main body 2 formed of a second material that has a larger linear expansion coefficient than that of the first material; and a roof panel edge 4A placed around the roof panel main body 2. The roof panel edge 4A includes a plurality of joined points to be joined to the vehicle upper part structure member BS. Moreover, the roof panel edge 4A includes at least one slit s which is present between at least one of the plurality of joined points and the roof panel main body 2 and which is extended so as to go over at least one joined point.SELECTED DRAWING: Figure 3

    【課題】意匠性の自由度を低下させることなく、車両の焼付塗装等を目的とする加熱時において、ルーフパネル意匠面の塑性変形を抑制し、外観品質不良を抑制することが可能な車両用ルーフパネルを提供する。【解決手段】第1の材料からなる車両上部構造部材BSと接合される車両用ルーフパネル1Aは、第1の材料の線膨張係数よりも大きな線膨張係数を有する第2の材料からなるルーフパネル本体部2と、ルーフパネル本体部2の周りに配置されるルーフパネル縁部4Aと、を備える。ルーフパネル縁部4Aは、車両上部構造部材BSと接合されるための複数の被接合点を有する。そして、ルーフパネル縁部4Aは、複数の被接合点のうちの少なくとも1つの被接合点とルーフパネル本体部2との間において、当該少なくとも1つの被接合点を跨ぐように、延びる少なくとも1つのスリットsを有する。【選択図】図3
