<p>In an iron-based powder, 0.01% to 5.0% by mass of oxide particles having an average size of 0.5 µm or more are contained, whereby the flowability of an iron-based mixed powder is increased and thereby the density of a green compact is increased, and ejection force is greatly reduced after compaction, thereby accomplishing an increase in product quality and a reduction in production cost.</p> |
