To miniaturize a casting apparatus at a low cost.

In this casting method using a pin 12 for cast hole penetrating a mold, at the time of solidifying molten metal in a mold 4, the pin 12 for cast hole is vibrated while cooling. Therefore, the pin 12 for cast hole being the vibrating body is hardly affected by the heat of the molten metal and the inexpensive material, such as aluminum and steel, as the material of the pin 12 for cast hole can be used. Further, since fining effect of metallic structure is large by the synergistic effect of the cooling and vibration, even in the case of setting the frequency of vibration low, the structure as the vibrating device 16 is simple and a small-sized device for low frequency can be used.
