Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a formwork for concrete molding and a manufacturing method thereof, which can reduce dents such as air pockmark appearing on a step of a concrete surface when concrete with a stepped surface is manufactured, and a manufacturing method of the concrete with a stepped surface.SOLUTION: A formwork 10 for concrete molding comprises: a form surface 20 with a stepped part 24 that can provide a step 26 on a concrete surface; and a porous layer 22, which is disposed at least on the stepped part 24 of the form surface 20 and is made from hydrophobic oxide particles.SELECTED DRAWING: Figure 1 【課題】表面に段差を有するコンクリートを製造する場合に、コンクリート表面の段差に生じる空気あばた等の窪みを低減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ならびに表面に段差を有するコンクリート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、コンクリート表面に段差２６を付与可能な段差部２４を有する型面２０と、この型面２０の少なくとも段差部２４に設けられ、疎水性酸化物微粒子から形成される多孔質層２２とを備えるようにする。【選択図】図１
