摘要： A forged product is made of a magnesium alloy and includes a through hole making portion to make a through hole that runs in a predetermined direction, and a bottom portion that lies on a plane intersecting with the predetermined direction. The through hole includes a first portion that has been formed by a forging process and a second portion that has been formed after the forging process. The second portion of the through hole has shifted toward the bottom portion with respect to the middle of the through hole in the predetermined direction.
