According to the present invention, an iron powder for dust cores, which has excellent compressibility and low iron loss after molding, can be obtained by setting the Si content thereof to 0.01 mass% or less, the apparent density thereof to 3.8 g/cm3 or more, the ratio of iron particles having a diameter of 45 μm or less to 10 mass% or less, the ratio of iron particles having a diameter of more than 180 μm but 250 μm or less to less than 30 mass%, the ratio of iron particles having a diameter of more than 250 μm to 10 mass% or less, and the Vickers hardness (test force: 0.245 N) in a particle cross-section to 80Hv or less. |
