Abstract
A raw material for thixomolding includes a magnesium-based alloy powder which contains calcium in an amount of 0.2 mass % or more and 5 mass % or less and aluminum in an amount of 2.5 mass % or more and 12 mass % or less, wherein the magnesium-based alloy powder includes an oxide layer which has an average thickness of 30 nm or more and 100 nm or less and contains at least one of calcium and aluminum as an outermost layer. The average dendrite secondary arm spacing of crystal structures of the magnesium-based alloy powder is preferably 5 μm or less.
