Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a liquid-repellent plastic molding that can maintain excellent liquid repellency for the long term, even if held in a state of being in constant contact with a liquid, especially a sticky fluid, and can be produced by a method applicable also to the field of packing material.SOLUTION: In a liquid-repellent plastic molding 1 that has a liquid-repellent surface, the liquid-repellent surface has a reentrant structure surface formed by an arrangement of pillars 20 each having an enlarged head 20a, and the reentrant structure surface at least partially includes a fluorine-containing surface with fluorine atoms dispersed therein.SELECTED DRAWING: Figure 3 【課題】液体、特に粘稠な流動体が常時接触している状態に保持されている場合にも、優れた撥液性が長期間にわたって維持され、しかも、包装材の分野にも適用可能な方法で製造し得る撥液性プラスチック成形体を提供する。【解決手段】撥液性表面を有する撥液性プラスチック成形体１において、前記撥液性表面は、拡径した頭部２０ａを有するピラー２０の配列により形成されたリエントラント構造表面を有しており、前記リエントラント構造表面の少なくとも一部には、フッ素原子が分布している含フッ素表面を有していることを特徴とする。【選択図】図３
