<P>PROBLEM TO BE SOLVED: To provide iron-based powder for powder metallurgy which has excellent flowability, can be uniformly filled into a thin-walled cavity, and can be compacted with low ejection force, while sustaining sufficient strength for a sintered body during a sintering process that follows the compaction process. Ž<P>SOLUTION: The iron-based powder for powder metallurgy is obtained by making a flowability improver particle containing 50 to 100 mass%, of carbon black adhere to the surface of an iron powder particle through a binder.
