description	PROBLEM TO BE SOLVED: To manufacture an internal chill body having a joining surface of the dimension and shape expected in the design by excellently filing the molten metal in the vicinity of a boundary part of a sand mold and an internal chill. SOLUTION: An internal chilled part 9 of an internal chill 7 is exposed in a cavity 5 of a sand mold 1 to form a heat storage part 10 projected in the cavity 5 from the sand mold 1 on a connection part of the sand mold 1 to the internal chilled part 9. When the molten metal is poured in the cavity 5, the heat of the molten metal in contact with the heat storage part 10 is stored in the heat storage part 10, and temperature drop of the molten metal in contact with the heat storage part 10 is controlled. Fluidity in the vicinity of the heat storage part 10 is kept excellently, and the molten metal is excellently filled in the vicinity of a boundary part 11 of the heat storage part 10 and the internal chilled part 9, and a joining surface of the size and shape approximately same as those expected in the design is formed between the internal chilled material and the material to be internal chilled in.
