PROBLEM TO BE SOLVED: To provide a vehicular upholstery which never provides brightness due to reflected light during drive and which may prevent window from displaying image of the upholstery, pattern etc.SOLUTION: There is provided a vehicular upholstery comprising low reflection structure part comprising a large number of projecting parts on its surface. Bottoms of the projecting parts have average maximum width passing gravity center of the bottom of within a range from 250 nm or more to 500 nm or less. Average distance between gravity centers of one of the projecting parts and another projecting part having bottom gravity center at the closest position to gravity center of the bottom of the one projecting part is 400 nm or less. Distribution in the distance between the gravity centers is 10000 nmor more. When position of top part of the projecting parts from gravity center of bottom is shown with an azimuthal angle φ (0°≤φ<360°) in plan view and extraction points of the projecting parts are defined as n(n≥30), the following formulae are satisfied: |Σcosφ/n|≤0.25; |Σsinφ/n|≤0.25.SELECTED DRAWING: Figure 5
【課題】運転中に反射光にて眩しさを感じることがなく、窓に内装材等の映像や模様等が映り込むことを防ぐことが可能な車両用内装材を提供することを主目的とする。【解決手段】表面に多数の突起部を備える低反射構造部を有する車両用内装材であって、上記突起部の底面は、上記底面の重心を通る最大幅の平均が250nm以上500nm以下の範囲内であり、一の上記突起部および上記一の突起部の底面の重心に最も近接した位置に底面の重心を有する他の上記突起部の重心間距離の平均が400nm以下であり、上記重心間距離の分散が10000nm2以上であり、平面視上において上記突起部の底面の重心からの上記突起部の頂部の位置を方位角φ(0°≦φ<360°)で示し、上記突起部の抽出点数をn(n≧30)としたときに、|Σ(k=1〜n)cosφk/n|≦0.25、かつ|Σ(k=1〜n)sinφk/n|≦0.25の関係を満たす。【選択図】図5
