Provided is a powder for metal molds that is less likely to cause solidification cracking even in a process involving rapid melt-quenching solidification. The powder for metal molds is made of an alloy. The alloy includes C: 0.25 mass % to 0.45 mass %, Si: 0.01 mass % to 1.20 mass %, Mn: more than 0 mass % to 1.50 mass %, Cr: 2.0 mass % to 5.5 mass %, and V: 0.2 mass % to 2.1 mass %. The alloy further includes at least one of Mo: more than 0 mass % to 3.0 mass %, W: more than 0 mass % to 9.5 mass %, and Co: more than 0 mass % to 4.5 mass %. The balance of the alloy is Fe and incidental impurities. The alloy satisfies the expression: (Mn %)3/S %>6.7. The total content of P, S and B in the alloy is 0.020 mass % or less.
