PROBLEM TO BE SOLVED: To provide a flame-retardant magnesium alloy in which the crystallization of Al<SB>2</SB>Ca is suppressed and the elongation of the alloy is improved and also cast-material strength, plastic workability and heat treatability are improved and also to provide its manufacturing method. SOLUTION: The flame-retardant magnesium alloy contains at least 1 to 12 mass% aluminum and 0.2 to 5.0 mass% calcium. The alloy can be obtained by melting magnesium, additive elements other than aluminum and calcium, and 0.2 to 5.0 mass% calcium, heating the resultant molten mixture to a temperature not lower than the melting temperature of Mg<SB>2</SB>Ca, and then adding 1 to 12 mass% aluminum to be subjected to solidification.
