To provide an embossed interior material having excellent scratch resistance, and capable of suppressing conspicuousness of flaws.SOLUTION: An embossed interior material 1 is provided with a resin base material 2 formed with an embossed pattern P. The resin base material is provided with: a base surface 3 extending in a first direction and a second direction; and a plurality of protrusions 4 protruded from the base surface 3 toward a third direction perpendicular to the first direction and the second direction. The protrusions are arranged on one side in the third direction with respect to the base surface, and each of the protrusions is provided with a top surface 5 extending in the first direction and the second direction, and a slope 6 with an inclination angle θ extending from the base surface toward the top surface. The embossed pattern P has a specified shape S provided with the plurality of protrusions spaced apart from each other. In the specified shape, in a view of a cross-section formed by cutting the resin base material in the third direction, a length a of an adjacent side with respect to the inclination angle of the slope, a length b of an opposite side to the inclination angle of the slope, a length c of the top surface, and a distance d between the protrusions adjacent to each other satisfy a relation of the following formula (1) to (2). b≤a≤3b (1), a≤c≤a+[d/2] (2).SELECTED DRAWING: Figure 2
【課題】耐傷性に優れ、かつ、傷の目立ちを抑制できる、シボ付内装材を提供する。【解決手段】シボ付内装材1はシボパターンPが形成された樹脂基材2を備える。樹脂基材は第1方向および第2方向に沿って延びる基面3と第1方向および第2方向に対して直交する第3方向に向かって基面3から突出する複数の凸部4とを備える。凸部は基面に対する第3方向一方側に配置され第1方向および第2方向に沿って延びる頂面5と基面から頂面に向かって延びる傾斜角θの斜面6とを備える。シボパターンPは互いに間隔が隔てられる複数の凸部を備える特定形状Sを有する。特定形状では樹脂基材を第3方向に切断した断面視において斜面の傾斜角に対する隣辺の長さaと斜面の傾斜角に対する対辺の長さbと頂面の長さcと互いに隣接する凸部間の距離dとが下記式(1)~(2)の関係を満たす。b≦a≦3b(1)、a≦c≦a+[d/2](2)【選択図】図2
