<P>PROBLEM TO BE SOLVED: To provide the technique which can easily draw out a pressure pin after a molten metal is solidified. Ž<P>SOLUTION: The casting device 10 is provided with a mold 12, a pressure pin 14 and a spray 26. The mold 12 includes a product cavity 22. The pressure pin 14 is provided so as to be progressed/retreated to the product cavity 22. The spray 26 sprays a mold releasing agent 24 comprising a shrinkage suppression material suppressing the shrinkage of a molten metal upon solidification by being melted in the molten metal toward the pressure pin 14, so as to allow the shrinkage suppression material to stick around the pressure pin 14.
