Abstract

A powder mixture of the present invention is characterized in that it comprises: an iron powder or an iron-based alloy powder, wherein a graphite powder is adhered to a surface of the iron powder or the iron-based alloy powder by a binding agent containing a polyolefin wax; and a negatively-charged powder to be mixed with the iron powder or the iron-based alloy powder, and consisting of an iron powder and/or an iron-based alloy powder treated for negatively charging. This enables keeping the good adhering property of a graphite powder in a mixed powder and high flowability as a mixture of the raw material powder.
