Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a mold for concrete molding which exerts excellent releasability persistently, allows repeated use and improves designability of concrete surfaces after molding and its production method.SOLUTION: A mold 10 for concrete molding has a porous layer 18 composed of a fine particle of a hydrophobic oxide, at least in a part of the mold surface 20. The fine particle of a hydrophobic oxide may be composed of hydrophobic silica, and the hydrophobic silica may have trimethylsilyl groups on the surface. 【課題】優れた離型性能を持続的に発揮できるとともに、繰り返し使用が可能で、成形後のコンクリート表面の意匠性を向上することができるコンクリート成形用型枠およびその製造方法を提供する。【解決手段】コンクリート成形用の型枠１０であって、型面２０の少なくとも一部に、疎水性酸化物微粒子から形成される多孔質層１８を備えるようにする。ここで、疎水性酸化物微粒子が疎水性シリカからなるようにしてもよく、疎水性シリカがその表面にトリメチルシリル基を有するようにしてもよい。【選択図】図１
