Abstract
The present invention relates to a magnesium alloy sheet comprising: 0.1 to 1.5 wt % of Zn, 0.08 to 0.7 wt % of Gd, a remainder of Mg, and other inevitable impurities with respect to an entire 100 wt % of the magnesium alloy sheet, and the magnesium alloy sheet may satisfy Relational Expression 1 below. [Zn]/[Gd]≥3.0 [Relational Expression 1] The [Zn] and [Gd] may indicate wt % of each component.
