PROBLEM TO BE SOLVED: To provide a casting package member for improving weight reduction in a molding body, by further increasing the effective cross-sectional area with metal formed as molten metal in casting package casting.SOLUTION: A casting package member 11 has a mesh-like projection part 3 on a casting packing surface 11S, and the mesh-like projection part 3 has a linear part 1 and an assembly part 2 for merging at least two linear parts. A manufacturing method of a casting package member includes at least a process of applying a coating mold agent to a surface for flowing in molten metal of a casting mold, a process of forming a coating mold layer having a crack shape on a surface by drying the coated coating mold agent and a process of casting while rotating the casting mold by flowing in the molten metal from above the coating mold layer.SELECTED DRAWING: Figure 1 【課題】鋳包み鋳造において、溶湯した金属との有効断面積がより大きく、且つ、成型体の軽量化を改善させる鋳包み用部材を提供する。【解決手段】鋳包まれる面１１Ｓ上に網目状の凸部３を有する鋳包み用部材１１であって、前記網目状の凸部３が、線状部分１と、少なくとも２つの線状部分が合流している集合部分２とを備える、鋳包み用部材１１、並びに鋳型の溶湯を流し込もうとする面に塗型剤を塗布する工程と、前記塗布した塗型剤を乾燥させて、表面にひび割れの形状を有する塗型層を形成する工程と、前記塗型層上から溶湯を流しこみ、前記鋳型を回転させながら鋳造する工程とを少なくとも含む、鋳包み用部材の製造方法。【選択図】図１
