Nozzle and layered object manufacturing apparatus

A nozzle for a layered object manufacturing apparatus, the nozzle comprising a body, wherein

• the body includes a first recess that opens to outside of the body, an internal bottom surface and an internal circumferential surface of the first recess, an output port from which an energy beam is output, and an ejection port from which powder of a material is ejected,
• the output port is provided on the internal bottom surface and opens to the first recess through which the energy beam passes,
• the ejection port is formed around the output port and opens to the first recess through which the powder passes, and
• an internal diameter of the internal circumferential surface becomes gradually smaller in a direction in which the energy beam is output from the output port to outside of the body through the first recess.
