To suppress adhesion of dirt.SOLUTION: There is provided a molded body containing a base resin and an additive which has lower melting point than melting point of the base resin and is a solid at an ordinary temperature, and having surface roughness Sa of 300 nm or less and falling angle of droplet on a surface of 90° or less. By effectively exposing an additive such as a lubricant to a molded body surface to make a surface to which droplet dirt or the like is difficult to be adhered, antifouling property can be largely improved.SELECTED DRAWING: Figure 7 【課題】汚れの付着を抑制することを課題とする。【解決手段】ベース樹脂と、ベース樹脂の融点より融点が低く、かつ常温で固体の添加剤を含有する成形体であって、表面粗さＳａが３００ｎｍ以下であり、かつ表面における液滴の転落角が９０°以下である成形体である。滑剤等の添加剤を成形体表面に有効に露出させ、液滴汚れ等が付着しにくい表面とすることにより、大幅な防汚性改善が見込める。【選択図】図７
