PROBLEM TO BE SOLVED: To make a gas (fluid) jet out at uniform temperature in the longitudinal direction of a nozzle. SOLUTION: A jet nozzle 20 is slender and has a hollow nozzle body 40. The body 40 has a plurality of nozzle orifices 42, extending in the longitudinal direction and an air inlet 44 of heated air. Inside the nozzle body 40, a first cylindrical body 45, that extends in the longitudinal direction and is made of a material, having thermal conductivity higher than that of the nozzle body 40, is assembled and is heated at temperature equal to that of the air heated by the heated air.
