PROBLEM TO BE SOLVED: To provide a casting method capable of preventing the defects of castings and the damage of pouring pins by reducing the sliding resistance between the castings and the pouring pins when inserting and removing the castings into and from the pouring pins. SOLUTION: Each of the pouring pins 1 is vibrated in the stage of inserting and removing the castings after the solidification of a molten metal and therefore, when the pouring pins are inserted and removed into the castings, the detachment effect of the castings and the pouring pins 1 can be promoted by sliding of the pouring pins 1. The sliding resistance of the castings and the pouring pins 1 is reduced, the damage of the surface treatment layers of the pouring pins 1 is suppressed and the faults, such as defects of the castings are prevented.
