An additive manufacturing head includes: a nozzle configured to discharge material powder; a rotary member connected with the nozzle, including a first material powder passage formed in the rotary member to direct the material powder to the nozzle, and configured to rotate to cause the nozzle to move in the circumferential direction about a laser beam emitted toward the workpiece; and a stationary member including a second material powder passage which is formed in the stationary member and into which the material powder is introduced, the stationary member being disposed directly beside the rotary member in the direction of the rotational axis of the rotary member. A third material powder passage communicating with the first material powder passage and the second material powder passage and extending annularly about the rotational axis of the rotary member is formed between the stationary member and the rotary member.
