  "textContent": "There is provided a lightweight, high strength impact-resistant component having a good impact energy absorptive property. The impact-resistant component is composed of a magnesium alloy containing Al in an amount of more than 7.3% by mass and 12% or less by mass. A rectangular test piece is produced from the impact-resistant component; an iron ball 30 having a mass of 225 g is allowed to freely fall toward a central portion of the test piece while both end portions of the test piece are fixed to supports 21 and 22; and, when a distance between a position from which the iron ball 30 is allowed to freely fall and the test piece is assumed to be a fall height, a fall height H at which a dent is not generated on the test piece by the iron ball 30 is measured. The impact-resistant component has a fall height H of more than 340 mm. In the impact-resistant component of the present invention, the fall height at which a dent is not generated is large. Therefore, the impact-resistant component of the present invention is not dented or is not easily dented even if an impact is applied and thus has high impact resistance.",
