<P>PROBLEM TO BE SOLVED: To provide a forging tool which has an inexpensive and simple configuration and can be continuously used for a long time by suppressing the collapse of a punch. Ž<P>SOLUTION: The forging tool includes a die 10 having a forming hole for a part to be formed by forging and the punch 30 so disposed as to face the die 10. In disposing a material 40 of a product to be forged in the forming hole of the die 10 and pressing the material 40 by the punch pressing section 30a of the punch 30 to form the forged product, a space section 50 for dispersing and absorbing a stress due to impact caused during the forging by positively promoting the elastic deformation of the punch pressing section 30a for deflecting that section is formed in the punch 30.
