Abstract
In an iron-based powder, 0.01% to 5.0% by mass of a flaky powder having an average particle size of longitudinal size of 100 or less, a thickness of 10 μm or less, and an aspect ratio (longitudinal size-to-thickness ratio) of 5 or more with respect to the iron-based mixed powder is contained, whereby the flowability of an iron-based mixed powder is increased, 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.
