PROBLEM TO BE SOLVED: To provide a blanking apparatus which is prevented from stopping caused by failure in gripping a product when gripping the product to feed it to the next stage, thereby can blank thin sheet materials at high speed and also can prevent the occurrence of abnormal goods caused by the deformation of the product. SOLUTION: After a blanking punch 3 is lowered and the thin sheet material 1 is blanked into a disk shape, a pin 4 is lowered and a blanked disk-shaped blank product 11 is dropped on a receiving base 6 which is formed on a die holder 5. At this time, because a vacuum switching valve of a vacuum forming apparatus is opened concurrently with lowering of the pin 4 and the blank product 11 is sucked in vacuum by a sucking hole through a sucking pipe 10 and a sucking passage 7, the blank product 11 is fixed on the receiving base 6 horizontally. Next, after elevating the blanking die 2 and gripping the blanked disk-shaped blank product 11 by fingers, the vacuum suction of the blank product 11 is released by closing the vacuum switching valve of the vacuum forming apparatus and the blank product is fed to the next stage by the fingers.
