PROBLEM TO BE SOLVED : To provide an easily formable magnesium alloy sheet having excellent formability, and to provide a method for production thereof. SOLUTION : The method for the production of an easily formable magnesium alloy sheet which has a pole in the sheet transverse direction of (0002) plane texture and exhibits an Erichsen value of 8.0 or above at ordinary temperature as a result, by subjecting either a magnesium alloy containing one or more light rare earth elements (Y, Sc, La, Ce, Pr, Nd, Sm), Zn, and, if necessary, Mn and/or Zr in prescribed amounts or a magnesium alloy containing Ca, Zn, and if necessary, one or more of Al, Mn and Zr in prescribed amounts to hot-or warm-rolling and then annealing under specified conditions; such an easily formable magnesium alloy sheet and articles made by using the same are also provided. Thus, the invention provides an easily formable magnesium alloy sheet positively applicable to press-formed members for household electrical appliances such as digital camera, notebook personal computer and PDA; and articles made by using the sheet.
