Zusammenfassung:	An additive-manufacturing head (21) is used for performing additive manufacturing by feeding a material to a workpiece and irradiating the workpiece with a laser beam. The additive-manufacturing head (21) includes: a ring-shape laser beam forming unit (32) configured to form a laser beam in a ring shape; a laser beam emitting unit (34) configured to emit the ring-shape laser beam toward a workpiece; and a material feeding unit (61) having an outlet (62) which is disposed inside the ring-shape laser beam emitted from the laser beam emitting unit (34) and from which the material is released, and configured to feed the material from the outlet (62) toward the workpiece. The head configured in this manner can improve the material usage efficiency for the directed energy deposition method.
