PROBLEM TO BE SOLVED: To provide a fastening structure for magnesium parts which is used under comparatively high temperature atmosphere, and in which a fastening axial force is hardly reduced at a low cost, with respect to the structure for fastening, with a bolt, the parts using the magnesium or the magnesium alloy. SOLUTION: When a second member 2 is fastened to a first member 1 composed of the magnesium or the magnesium alloy by using the metal-made bolt 3, a metal member 4 composed of an iron-base material and an aluminum alloy or a heat-resistant magnesium alloy and provided with a fall-out preventive means and a rotating preventive means from the first member 1 together with a female-screw part 4a for screwing to the metal-made bolt 3 is cast in the first member 1 to make the cast-in part and the bolt 3 passed through a bolt inserting hole 2a formed in the second member 2 is fastened into the female-screw part 4a in the cast-in part 4.
