To provide a nozzle capable of supplying powder to a finer area.SOLUTION: A nozzle according to one embodiment has an inner surface and an outer surface facing the inner surface, and is provided with a first passage through which energy rays pass, and a second passage through which powder and fluid pass and which is provided between the inner surface and the outer surface. The second passage includes a second open end located at an end of the second passage in a first direction. A first surface of one of the inner surface and the outer surface includes a first edge located at an end of the first surface in the first direction. A second surface of other of the inner surface and the outer surface is located at an end of the second surface in the first direction, and includes a second edge spaced apart from the first edge in the first direction in a direction along a central axis. The fluid discharged from the second open end flows along the second surface and causes peeling at the second edge.SELECTED DRAWING: Figure 2 【課題】より微細な領域に粉体を供給することができるノズルを提供する。【解決手段】一つの実施形態に係るノズルは、内側面と、前記内側面に向く外側面と、を有し、エネルギー線が通る第１の通路と、前記内側面と前記外側面との間に設けられ、粉体及び流体が通る、第２の通路と、が設けられる。前記第２の通路は、第１の方向における当該第２の通路の端に位置する第２の開口端を含む。前記内側面と前記外側面とのうち一方の第１の面は、前記第１の方向における当該第１の面の端に位置する第１の端縁を含む。前記内側面と前記外側面とのうち他方の第２の面は、前記第１の方向における当該第２の面の端に位置するとともに前記中心軸に沿う方向において前記第１の端縁から前記第１の方向に離間する第２の端縁を含む。前記第２の開口端から吐出された前記流体が、前記第２の面に沿って流れ、前記第２の端縁で剥離を生じる。【選択図】図２
