PROBLEM TO BE SOLVED: To provide a single crystal laminating method capable of simply imparting a complicated over-hanging shape to a casting product such as a turbine. SOLUTION: As for the single crystal laminating method, in the preformed single crystal body (base material) 100, a shape-giving mold 101 is allowed rto abut on the place for forming the over-hanging single crystal, then the same single crystal as the single crystal body 100 is laminated on the base material 100 while controlling the crystal while forming a fused pond 110 in the shape-giving mold 101 with a heating source 111, and then, the mold 101 is taken out, thereby obtaining a product having the same single crystal over-hanging part 102 as the base material 100.
