PROBLEM TO BE SOLVED: To provide a molding having an excellent appearance free from filler lifting or appearance unevenness, without applying coating.SOLUTION: A resin molding including a filler has a convexoconcave shape on a surface thereof. The convexoconcave shape has arithmetic average roughness of 0.8 to 10 μm. A peak of the convexoconcave shape has arithmetic average curvature of 400[1/mm] to 900[1/mm].SELECTED DRAWING: Figure 2 【課題】 塗装を行なわなくても、フィラー浮きや外観ムラの無い良好な外観を有する成形品を得る。【解決手段】 フィラーを含む樹脂成形品において、表面に凹凸形状が形成されており、前記凹凸形状は、算術平均粗さが０．８μｍ以上１０μｍ以下であり、前記凹凸形状の山頂点の算術平均曲率が４００［１／ｍｍ］以上９００［１／ｍｍ］以下であることを特徴とする。【選択図】 図２
