Zusammenfassung:	The present invention proposes a production method for reduced iron that makes it possible to prevent clustering when a shaft furnace or a kiln furnace is used to reduce a reduction starting material by means of a reducing gas to obtain reduced iron. A production method according to the present invention involves using a shaft furnace or a kiln furnace to reduce a reduction starting material by means of a reducing gas to obtain reduced iron. The reduction starting material includes sintered ore. The reduction starting material preferably consists of: no more than 80 mass% of the sintered ore; and at least one of residual lump ore and pellets.
