PROBLEM TO BE SOLVED: To provide a mold and a structural body for producing a casting, having good formability and light weight and sufficient hot-strength and shape-holding property at the casting time and excellent surface smoothness of the casting and excellent removability after casting. SOLUTION: This mold and structural body includes an organic fiber, an inorganic fiber and a thermosetting resin. It is desirable that the above organic fiber is a paper fiber and the above inorganic fiber is a carbon fiber and the above thermosetting resin is a phenolic resin. A blending ratio of the above organic fiber, inorganic fiber and thermosetting resin is desirably 10-70/1-80/10-70 (weight ratio). COPYRIGHT: (C)2004,JPO&NCIPI
