Abstract
Provided are an iron-based mixed powder and an oxygen reactant that are easily producible, have high reactivity with oxygen, and suppress hydrogen gas generation. An iron-based mixed powder consists of: an iron-based powder having an atomic ratio O/Fe of oxygen to iron of 0.800 or less; and a sulfur-containing powder having a sulfur content of 10.000 mass % or more and 100.000 mass % or less, wherein content of the sulfur-containing powder is 0.020 mass % or more and 5.000 mass % or less relative to total content of the iron-based powder and the sulfur-containing powder.
