Summary:PROBLEM TO BE SOLVED: To provide a mold capable of reducing or preventing sticking of a mold material of a mold on a cast surface by preventing temperature rise, and maintaining the quality of the cast surface; and to provide a manufacturing method of the mold.SOLUTION: A mold 1 includes: a heat radiation material 10, which is a material having higher heat conductivity than a mold material and passable by gas generated from a molten metal, and which is arranged near a boundary surface with a cavity 4 into which the molten metal is poured; and a surface molding part 3A comprising the mold material, and arranged on the furthermore boundary surface side with the cavity 4 than the radiation material 10.SELECTED DRAWING: Figure 1 【課題】高温化を抑制して、鋳型の鋳型材が鋳造品表面に焼付くことを低減又は防止でき、かつ、鋳造品表面の品質を維持することが可能な鋳型及び鋳型の製造方法を提供することを目的とする。【解決手段】鋳型１は、鋳型材よりも熱伝導率が高く、溶融金属にて発生するガスが通過する材料であり、溶融金属が流し込まれるキャビティ４との境界面近傍に配置される放熱材１０と、鋳型材からなり、放熱材１０よりもキャビティ４との境界面側に配置される表面鋳型部３Ａとを備える。【選択図】図１
